Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mdiobus: fix unbalanced node reference count
I got the following report while doing device(mscc-miim) load test
with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:
OF: ERROR: memory leak, expected refcount 1 instead of 2,
of_node_get()/of_node_put() unbalanced - destroy cset entry:
attach overlay node /spi/soc@0/mdio@7107009c/ethernet-phy@0
If the 'fwnode' is not an acpi node, the refcount is get in
fwnode_mdiobus_phy_device_register(), but it has never been
put when the device is freed in the normal path. So call
fwnode_handle_put() in phy_device_release() to avoid leak.
If it's an acpi node, it has never been get, but it's put
in the error path, so call fwnode_handle_get() before
phy_device_register() to keep get/put operation balanced.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: health: afe4404: Fix oob read in afe4404_[read|write]_raw
KASAN report out-of-bounds read as follows:
BUG: KASAN: global-out-of-bounds in afe4404_read_raw+0x2ce/0x380
Read of size 4 at addr ffffffffc00e4658 by task cat/278
Call Trace:
afe4404_read_raw
iio_read_channel_info
dev_attr_show
The buggy address belongs to the variable:
afe4404_channel_leds+0x18/0xffffffffffffe9c0
This issue can be reproduce by singe command:
$ cat /sys/bus/i2c/devices/0-0058/iio\:device0/in_intensity6_raw
The array size of afe4404_channel_leds and afe4404_channel_offdacs
are less than channels, so access with chan->address cause OOB read
in afe4404_[read|write]_raw. Fix it by moving access before use them.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: cancel dqi_sync_work before freeing oinfo
ocfs2_global_read_info() will initialize and schedule dqi_sync_work at the
end, if error occurs after successfully reading global quota, it will
trigger the following warning with CONFIG_DEBUG_OBJECTS_* enabled:
ODEBUG: free active (active state 0) object: 00000000d8b0ce28 object type: timer_list hint: qsync_work_fn+0x0/0x16c
This reports that there is an active delayed work when freeing oinfo in
error handling, so cancel dqi_sync_work first. BTW, return status instead
of -1 when .read_file_info fails.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: edia: dvbdev: fix a use-after-free
In dvb_register_device, *pdvbdev is set equal to dvbdev, which is freed
in several error-handling paths. However, *pdvbdev is not set to NULL
after dvbdev's deallocation, causing use-after-frees in many places,
for example, in the following call chain:
budget_register
|-> dvb_dmxdev_init
|-> dvb_register_device
|-> dvb_dmxdev_release
|-> dvb_unregister_device
|-> dvb_remove_device
|-> dvb_device_put
|-> kref_put
When calling dvb_unregister_device, dmxdev->dvbdev (i.e. *pdvbdev in
dvb_register_device) could point to memory that had been freed in
dvb_register_device. Thereafter, this pointer is transferred to
kref_put and triggering a use-after-free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix potential oob read in nilfs_btree_check_delete()
The function nilfs_btree_check_delete(), which checks whether degeneration
to direct mapping occurs before deleting a b-tree entry, causes memory
access outside the block buffer when retrieving the maximum key if the
root node has no entries.
This does not usually happen because b-tree mappings with 0 child nodes
are never created by mkfs.nilfs2 or nilfs2 itself. However, it can happen
if the b-tree root node read from a device is configured that way, so fix
this potential issue by adding a check for that case.

ieee802154_if_add() allocates wpan_dev as netdev's private data, but not
init the list in struct wpan_dev. cfg802154_netdev_notifier_call() manage
the list when device register/unregister, and may lead to null-ptr-deref.
Use INIT_LIST_HEAD() on it to initialize it correctly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: pca953x: fix pca953x_irq_bus_sync_unlock race
Ensure that `i2c_lock' is held when setting interrupt latch and mask in
pca953x_irq_bus_sync_unlock() in order to avoid races.
The other (non-probe) call site pca953x_gpio_set_multiple() ensures the
lock is held before calling pca953x_write_regs().
The problem occurred when a request raced against irq_bus_sync_unlock()
approximately once per thousand reboots on an i.MX8MP based system.
* Normal case

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: asihpi: Fix potential OOB array access
ASIHPI driver stores some values in the static array upon a response
from the driver, and its index depends on the firmware. We shouldn't
trust it blindly.
This patch adds a sanity check of the array index to fit in the array
size.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: battery: Fix possible crash when unregistering a battery hook
When a battery hook returns an error when adding a new battery, then
the battery hook is automatically unregistered.
However the battery hook provider cannot know that, so it will later
call battery_hook_unregister() on the already unregistered battery
hook, resulting in a crash.
Fix this by using the list head to mark already unregistered battery
hooks as already being unregistered so that they can be ignored by
battery_hook_unregister().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: avoid reading out of bounds when loading TX power FW elements
Because the loop-expression will do one more time before getting false from
cond-expression, the original code copied one more entry size beyond valid
region.
Fix it by moving the entry copy to loop-body.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: ops: Check bounds for second channel in snd_soc_put_volsw_sx()
The bounds checks in snd_soc_put_volsw_sx() are only being applied to the
first channel, meaning it is possible to write out of bounds values to the
second channel in stereo controls. Add appropriate checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix crash caused by calling __xfrm_state_delete() twice
The km.state is not checked in driver's delayed work. When
xfrm_state_check_expire() is called, the state can be reset to
XFRM_STATE_EXPIRED, even if it is XFRM_STATE_DEAD already. This
happens when xfrm state is deleted, but not freed yet. As
__xfrm_state_delete() is called again in xfrm timer, the following
crash occurs.
To fix this issue, skip xfrm_state_check_expire() if km.state is not
XFRM_STATE_VALID.

Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring: check if we need to reschedule during overflow flush
In terms of normal application usage, this list will always be empty.
And if an application does overflow a bit, it'll have a few entries.
However, nothing obviously prevents syzbot from running a test case
that generates a ton of overflow entries, and then flushing them can
take quite a while.
Check for needing to reschedule while flushing, and drop our locks and
do so if necessary. There's no state to maintain here as overflows
always prune from head-of-list, hence it's fine to drop and reacquire
the locks at the end of the loop.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix macvlan leak by synchronizing access to mac_filter_hash
This patch addresses a macvlan leak issue in the i40e driver caused by
concurrent access to vsi->mac_filter_hash. The leak occurs when multiple
threads attempt to modify the mac_filter_hash simultaneously, leading to
inconsistent state and potential memory leaks.
To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing
vf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock),
ensuring atomic operations and preventing concurrent access.
Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) in
i40e_add_mac_filter() to help catch similar issues in the future.
Reproduction steps:
1. Spawn VFs and configure port vlan on them.
2. Trigger concurrent macvlan operations (e.g., adding and deleting
portvlan and/or mac filters).
3. Observe the potential memory leak and inconsistent state in the
mac_filter_hash.
This synchronization ensures the integrity of the mac_filter_hash and prevents
the described leak.

The leak occurs when multiple\nthreads attempt to modify the mac_filter_hash simultaneously, leading to\ninconsistent state and potential memory leaks.\n\nTo fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing\nvf-\u003edefault_lan_addr.addr with spin_lock/unlock_bh(\u0026vsi-\u003emac_filter_hash_lock),\nensuring atomic operations and preventing concurrent access.\n\nAdditionally, we add lockdep_assert_held(\u0026vsi-\u003emac_filter_hash_lock) in\ni40e_add_mac_filter() to help catch similar issues in the future.\n\nReproduction steps:\n1. Spawn VFs and configure port vlan on them.\n2. Trigger concurrent macvlan operations (e.g., adding and deleting\n\tportvlan and/or mac filters).\n3. Observe the potential memory leak and inconsistent state in the\n\tmac_filter_hash.\n\nThis synchronization ensures the integrity of the mac_filter_hash and prevents\nthe described leak."

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: fix out-of-bounds in dbNextAG() and diAlloc()
In dbNextAG() , there is no check for the case where bmp->db_numag is
greater or same than MAXAG due to a polluted image, which causes an
out-of-bounds. Therefore, a bounds check should be added in dbMount().
And in dbNextAG(), a check for the case where agpref is greater than
bmp->db_numag should be added, so an out-of-bounds exception should be
prevented.
Additionally, a check for the case where agno is greater or same than
MAXAG should be added in diAlloc() to prevent out-of-bounds.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dpaa: Pad packets to ETH_ZLEN
When sending packets under 60 bytes, up to three bytes of the buffer
following the data may be leaked. Avoid this by extending all packets to
ETH_ZLEN, ensuring nothing is leaked in the padding. This bug can be
reproduced by running
$ ping -s 11 destination

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: keystone: Add workaround for Errata #i2037 (AM65x SR 1.0)
Errata #i2037 in AM65x/DRA80xM Processors Silicon Revision 1.0
(SPRZ452D_July 2018_Revised December 2019 [1]) mentions when an
inbound PCIe TLP spans more than two internal AXI 128-byte bursts,
the bus may corrupt the packet payload and the corrupt data may
cause associated applications or the processor to hang.
The workaround for Errata #i2037 is to limit the maximum read
request size and maximum payload size to 128 bytes. Add workaround
for Errata #i2037 here.
The errata and workaround is applicable only to AM65x SR 1.0 and
later versions of the silicon will have this fixed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vt: prevent kernel-infoleak in con_font_get()
font.data may not initialize all memory spaces depending on the implementation
of vc->vc_sw->con_font_get. This may cause info-leak, so to prevent this, it
is safest to modify it to initialize the allocated memory space to 0, and it
generally does not affect the overall performance of the system.

Summary
In the Linux kernel, the following vulnerability has been resolved:
driver core: Fix a potential null-ptr-deref in module_add_driver()
Inject fault while probing of-fpga-region, if kasprintf() fails in
module_add_driver(), the second sysfs_remove_link() in exit path will cause
null-ptr-deref as below because kernfs_name_hash() will call strlen() with
NULL driver_name.
Fix it by releasing resources based on the exit path sequence.
KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: Fix use-after-free when reverting termination table
When having multiple dests with termination tables and second one
or afterwards fails the driver reverts usage of term tables but
doesn't reset the assignment in attr->dests[num_vport_dests].termtbl
which case a use-after-free when releasing the rule.
Fix by resetting the assignment of termtbl to null.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: add bounds checking to ocfs2_xattr_find_entry()
Add a paranoia check to make sure it doesn't stray beyond valid memory
region containing ocfs2 xattr entries when scanning for a match. It will
prevent out-of-bound access in case of crafted images.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-fabrics: use reserved tag for reg read/write command
In some scenarios, if too many commands are issued by nvme command in
the same time by user tasks, this may exhaust all tags of admin_q. If
a reset (nvme reset or IO timeout) occurs before these commands finish,
reconnect routine may fail to update nvme regs due to insufficient tags,
which will cause kernel hang forever. In order to workaround this issue,
maybe we can let reg_read32()/reg_read64()/reg_write32() use reserved
tags. This maybe safe for nvmf:
1. For the disable ctrl path, we will not issue connect command
2. For the enable ctrl / fw activate path, since connect and reg_xx()
are called serially.
So the reserved tags may still be enough while reg_xx() use reserved tags.

Summary
In the Linux kernel, the following vulnerability has been resolved:
resource: fix region_intersects() vs add_memory_driver_managed()
On a system with CXL memory, the resource tree (/proc/iomem) related to
CXL memory may look like something as follows.
490000000-50fffffff : CXL Window 0
490000000-50fffffff : region0
490000000-50fffffff : dax0.0
490000000-50fffffff : System RAM (kmem)
Because drivers/dax/kmem.c calls add_memory_driver_managed() during
onlining CXL memory, which makes "System RAM (kmem)" a descendant of "CXL
Window X". This confuses region_intersects(), which expects all "System
RAM" resources to be at the top level of iomem_resource. This can lead to
bugs.
For example, when the following command line is executed to write some
memory in CXL memory range via /dev/mem,
$ dd if=data of=/dev/mem bs=$((1 << 10)) seek=$((0x490000000 >> 10)) count=1
dd: error writing '/dev/mem': Bad address
1+0 records in
0+0 records out
0 bytes copied, 0.0283507 s, 0.0 kB/s
the command fails as expected. However, the error code is wrong. It
should be "Operation not permitted" instead of "Bad address". More
seriously, the /dev/mem permission checking in devmem_is_allowed() passes
incorrectly. Although the accessing is prevented later because ioremap()
isn't allowed to map system RAM, it is a potential security issue. During
command executing, the following warning is reported in the kernel log for
calling ioremap() on system RAM.
ioremap on RAM at 0x0000000490000000 - 0x0000000490000fff
WARNING: CPU: 2 PID: 416 at arch/x86/mm/ioremap.c:216 __ioremap_caller.constprop.0+0x131/0x35d
Call Trace:
memremap+0xcb/0x184
xlate_dev_mem_ptr+0x25/0x2f

ksys_write+0xac/0xfe
do_syscall_64+0x9a/0xfd
entry_SYSCALL_64_after_hwframe+0x4b/0x53
The details of command execution process are as follows. In the above
resource tree, "System RAM" is a descendant of "CXL Window 0" instead of a
top level resource. So, region_intersects() will report no System RAM
resources in the CXL memory region incorrectly, because it only checks the
top level resources. Consequently, devmem_is_allowed() will return 1
(allow access via /dev/mem) for CXL memory region incorrectly.
Fortunately, ioremap() doesn't allow to map System RAM and reject the
access.
So, region_intersects() needs to be fixed to work correctly with the
resource tree with "System RAM" not at top level as above. To fix it, if
we found a unmatched resource in the top level, we will continue to search
matched resources in its descendant resources. So, we will not miss any
matched resources in resource tree anymore.
In the new implementation, an example resource tree
|------------- "CXL Window 0" ------------|
|-- "System RAM" --|
will behave similar as the following fake resource tree for
region_intersects(, IORESOURCE_SYSTEM_RAM, ),
|-- "System RAM" --||-- "CXL Window 0a" --|
Where "CXL Window 0a" is part of the original "CXL Window 0" that
isn't covered by "System RAM".

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix helper writes to read-only maps
Lonial found an issue that despite user- and BPF-side frozen BPF map
(like in case of .rodata), it was still possible to write into it from
a BPF program side through specific helpers having ARG_PTR_TO_{LONG,INT}
as arguments.
In check_func_arg() when the argument is as mentioned, the meta->raw_mode
is never set. Later, check_helper_mem_access(), under the case of
PTR_TO_MAP_VALUE as register base type, it assumes BPF_READ for the
subsequent call to check_map_access_type() and given the BPF map is
read-only it succeeds.
The helpers really need to be annotated as ARG_PTR_TO_{LONG,INT} | MEM_UNINIT
when results are written into them as opposed to read out of them. The
latter indicates that it's okay to pass a pointer to uninitialized memory
as the memory is written to anyway.
However, ARG_PTR_TO_{LONG,INT} is a special case of ARG_PTR_TO_FIXED_SIZE_MEM
just with additional alignment requirement. So it is better to just get
rid of the ARG_PTR_TO_{LONG,INT} special cases altogether and reuse the
fixed size memory types. For this, add MEM_ALIGNED to additionally ensure
alignment given these helpers write directly into the args via *<ptr> = val.
The .arg*_size has been initialized reflecting the actual sizeof(*<ptr>).
MEM_ALIGNED can only be used in combination with MEM_FIXED_SIZE annotated
argument types, since in !MEM_FIXED_SIZE cases the verifier does not know
the buffer size a priori and therefore cannot blindly write *<ptr> = val.

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched: sch_cake: fix bulk flow accounting logic for host fairness
In sch_cake, we keep track of the count of active bulk flows per host,
when running in dst/src host fairness mode, which is used as the
round-robin weight when iterating through flows. The count of active
bulk flows is updated whenever a flow changes state.
This has a peculiar interaction with the hash collision handling: when a
hash collision occurs (after the set-associative hashing), the state of
the hash bucket is simply updated to match the new packet that collided,
and if host fairness is enabled, that also means assigning new per-host
state to the flow. For this reason, the bulk flow counters of the
host(s) assigned to the flow are decremented, before new state is
assigned (and the counters, which may not belong to the same host
anymore, are incremented again).
Back when this code was introduced, the host fairness mode was always
enabled, so the decrement was unconditional. When the configuration
flags were introduced the *increment* was made conditional, but
the *decrement* was not. Which of course can lead to a spurious
decrement (and associated wrap-around to U16_MAX).
AFAICT, when host fairness is disabled, the decrement and wrap-around
happens as soon as a hash collision occurs (which is not that common in
itself, due to the set-associative hashing). However, in most cases this
is harmless, as the value is only used when host fairness mode is
enabled. So in order to trigger an array overflow, sch_cake has to first
be configured with host fairness disabled, and while running in this
mode, a hash collision has to occur to cause the overflow. Then, the
qdisc has to be reconfigured to enable host fairness, which leads to the
array out-of-bounds because the wrapped-around value is retained and
used as an array index. It seems that syzbot managed to trigger this,
which is quite impressive in its own right.
This patch fixes the issue by introducing the same conditional check on
decrement as is used on increment.
The original bug predates the upstreaming of cake, but the commit listed
in the Fixes tag touched that code, meaning that this patch won't apply
before that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix a sdiv overflow issue
Zac Ecob reported a problem where a bpf program may cause kernel crash due
to the following error:
Oops: divide error: 0000 [#1] PREEMPT SMP KASAN PTI
The failure is due to the below signed divide:
LLONG_MIN/-1 where LLONG_MIN equals to -9,223,372,036,854,775,808.
LLONG_MIN/-1 is supposed to give a positive number 9,223,372,036,854,775,808,
but it is impossible since for 64-bit system, the maximum positive
number is 9,223,372,036,854,775,807. On x86_64, LLONG_MIN/-1 will
cause a kernel exception. On arm64, the result for LLONG_MIN/-1 is
LLONG_MIN.
Further investigation found all the following sdiv/smod cases may trigger
an exception when bpf program is running on x86_64 platform:
- LLONG_MIN/-1 for 64bit operation
- INT_MIN/-1 for 32bit operation
- LLONG_MIN%-1 for 64bit operation
- INT_MIN%-1 for 32bit operation
where -1 can be an immediate or in a register.
On arm64, there are no exceptions:
- LLONG_MIN/-1 = LLONG_MIN
- INT_MIN/-1 = INT_MIN
- LLONG_MIN%-1 = 0
- INT_MIN%-1 = 0
where -1 can be an immediate or in a register.
Insn patching is needed to handle the above cases and the patched codes
produced results aligned with above arm64 result. The below are pseudo
codes to handle sdiv/smod exceptions including both divisor -1 and divisor 0
and the divisor is stored in a register.
sdiv:
tmp = rX
tmp += 1 /* [-1, 0] -> [0, 1]
if tmp >(unsigned) 1 goto L2
if tmp == 0 goto L1
rY = 0
L1:
rY = -rY;
goto L3
L2:
rY /= rX
L3:
smod:
tmp = rX
tmp += 1 /* [-1, 0] -> [0, 1]
if tmp >(unsigned) 1 goto L1
if tmp == 1 (is64 ? goto L2 : goto L3)
rY = 0;
goto L2
L1:
rY %= rX
L2:
goto L4 // only when !is64
L3:
wY = wY // only when !is64

Summary
In the Linux kernel, the following vulnerability has been resolved:
ALSA: seq: Fix function prototype mismatch in snd_seq_expand_var_event
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed.
seq_copy_in_user() and seq_copy_in_kernel() did not have prototypes
matching snd_seq_dump_func_t. Adjust this and remove the casts. There
are not resulting binary output differences.
This was found as a result of Clang's new -Wcast-function-type-strict
flag, which is more sensitive than the simpler -Wcast-function-type,
which only checks for type width mismatches.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nouveau/dmem: handle kcalloc() allocation failure
The kcalloc() in nouveau_dmem_evict_chunk() will return null if
the physical memory has run out. As a result, if we dereference
src_pfns, dst_pfns or dma_addrs, the null pointer dereference bugs
will happen.
Moreover, the GPU is going away. If the kcalloc() fails, we could not
evict all pages mapping a chunk. So this patch adds a __GFP_NOFAIL
flag in kcalloc().
Finally, as there is no need to have physically contiguous memory,
this patch switches kcalloc() to kvcalloc() in order to avoid
failing allocations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/core: Implement a limit on UMAD receive List
The existing behavior of ib_umad, which maintains received MAD
packets in an unbounded list, poses a risk of uncontrolled growth.
As user-space applications extract packets from this list, the rate
of extraction may not match the rate of incoming packets, leading
to potential list overflow.
To address this, we introduce a limit to the size of the list. After
considering typical scenarios, such as OpenSM processing, which can
handle approximately 100k packets per second, and the 1-second retry
timeout for most packets, we set the list size limit to 200k. Packets
received beyond this limit are dropped, assuming they are likely timed
out by the time they are handled by user-space.
Notably, packets queued on the receive list due to reasons like
timed-out sends are preserved even when the list is full.

After\nconsidering typical scenarios, such as OpenSM processing, which can\nhandle approximately 100k packets per second, and the 1-second retry\ntimeout for most packets, we set the list size limit to 200k. Packets\nreceived beyond this limit are dropped, assuming they are likely timed\nout by the time they are handled by user-space.\n\nNotably, packets queued on the receive list due to reasons like\ntimed-out sends are preserved even when the list is full."

Summary
In the Linux kernel, the following vulnerability has been resolved:
apparmor: fix possible NULL pointer dereference
profile->parent->dents[AAFS_PROF_DIR] could be NULL only if its parent is made
from __create_missing_ancestors(..) and 'ent->old' is NULL in
aa_replace_profiles(..).
In that case, it must return an error code and the code, -ENOENT represents
its state that the path of its parent is not existed yet.

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal: core: Free tzp copy along with the thermal zone
The object pointed to by tz->tzp may still be accessed after being
freed in thermal_zone_device_unregister(), so move the freeing of it
to the point after the removal completion has been completed at which
it cannot be accessed any more.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix double brelse() the buffer of the extents path
In ext4_ext_try_to_merge_up(), set path[1].p_bh to NULL after it has been
released, otherwise it may be released twice. An example of what triggers
this is as follows:
split2 map split1
|--------|-------|--------|
ext4_ext_map_blocks
ext4_ext_handle_unwritten_extents
ext4_split_convert_extents
// path->p_depth == 0
ext4_split_extent
// 1. do split1
ext4_split_extent_at
|ext4_ext_insert_extent
| ext4_ext_create_new_leaf
| ext4_ext_grow_indepth
| le16_add_cpu(&neh->eh_depth, 1)
| ext4_find_extent
| // return -ENOMEM
|// get error and try zeroout
|path = ext4_find_extent
| path->p_depth = 1
|ext4_ext_try_to_merge
| ext4_ext_try_to_merge_up
| path->p_depth = 0
| brelse(path[1].p_bh) ---> not set to NULL here
|// zeroout success
// 2. update path
ext4_find_extent
// 3. do split2
ext4_split_extent_at
ext4_ext_insert_extent
ext4_ext_create_new_leaf
ext4_ext_grow_indepth
le16_add_cpu(&neh->eh_depth, 1)
ext4_find_extent
path[0].p_bh = NULL;
path->p_depth = 1
read_extent_tree_block ---> return err
// path[1].p_bh is still the old value
ext4_free_ext_path
ext4_ext_drop_refs
// path->p_depth == 1
brelse(path[1].p_bh) ---> brelse a buffer twice
Finally got the following WARRNING when removing the buffer from lru:

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: x86-android-tablets: Fix use after free on platform_device_register() errors
x86_android_tablet_remove() frees the pdevs[] array, so it should not
be used after calling x86_android_tablet_remove().
When platform_device_register() fails, store the pdevs[x] PTR_ERR() value
into the local ret variable before calling x86_android_tablet_remove()
to avoid using pdevs[] after it has been freed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: prevent potential speculation leaks in gpio_device_get_desc()
Userspace may trigger a speculative read of an address outside the gpio
descriptor array.
Users can do that by calling gpio_ioctl() with an offset out of range.
Offset is copied from user and then used as an array index to get
the gpio descriptor without sanitization in gpio_device_get_desc().
This change ensures that the offset is sanitized by using
array_index_nospec() to mitigate any possibility of speculative
information leaks.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: clean up our handling of refs == 0 in snapshot delete
In reada we BUG_ON(refs == 0), which could be unkind since we aren't
holding a lock on the extent leaf and thus could get a transient
incorrect answer. In walk_down_proc we also BUG_ON(refs == 0), which
could happen if we have extent tree corruption. Change that to return
-EUCLEAN. In do_walk_down() we catch this case and handle it correctly,
however we return -EIO, which -EUCLEAN is a more appropriate error code.
Finally in walk_up_proc we have the same BUG_ON(refs == 0), so convert
that to proper error handling. Also adjust the error message so we can
actually do something with the information.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()
As comment of pci_get_domain_bus_and_slot() says, it returns
a pci device with refcount increment, when finish using it,
the caller must decrement the reference count by calling
pci_dev_put(). So call it after using to avoid refcount leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
firmware_loader: Block path traversal
Most firmware names are hardcoded strings, or are constructed from fairly
constrained format strings where the dynamic parts are just some hex
numbers or such.
However, there are a couple codepaths in the kernel where firmware file
names contain string components that are passed through from a device or
semi-privileged userspace; the ones I could find (not counting interfaces
that require root privileges) are:
- lpfc_sli4_request_firmware_update() seems to construct the firmware
filename from "ModelName", a string that was previously parsed out of
some descriptor ("Vital Product Data") in lpfc_fill_vpd()
- nfp_net_fw_find() seems to construct a firmware filename from a model
name coming from nfp_hwinfo_lookup(pf->hwinfo, "nffw.partno"), which I
think parses some descriptor that was read from the device.
(But this case likely isn't exploitable because the format string looks
like "netronome/nic_%s", and there shouldn't be any *folders* starting
with "netronome/nic_". The previous case was different because there,
the "%s" is *at the start* of the format string.)
- module_flash_fw_schedule() is reachable from the
ETHTOOL_MSG_MODULE_FW_FLASH_ACT netlink command, which is marked as
GENL_UNS_ADMIN_PERM (meaning CAP_NET_ADMIN inside a user namespace is
enough to pass the privilege check), and takes a userspace-provided
firmware name.
(But I think to reach this case, you need to have CAP_NET_ADMIN over a
network namespace that a special kind of ethernet device is mapped into,
so I think this is not a viable attack path in practice.)
Fix it by rejecting any firmware names containing ".." path components.
For what it's worth, I went looking and haven't found any USB device
drivers that use the firmware loader dangerously.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix race on per-CQ variable napi work_done
After calling napi_complete_done(), the NAPIF_STATE_SCHED bit may be
cleared, and another CPU can start napi thread and access per-CQ variable,
cq->work_done. If the other thread (for example, from busy_poll) sets
it to a value >= budget, this thread will continue to run when it should
stop, and cause memory corruption and panic.
To fix this issue, save the per-CQ work_done variable in a local variable
before napi_complete_done(), so it won't be corrupted by a possible
concurrent thread after napi_complete_done().
Also, add a flag bit to advertise to the NIC firmware: the NAPI work_done
variable race is fixed, so the driver is able to reliably support features
like busy_poll.

Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with
active RSS contexts") proves that allowing indirection table to contain
channels with out of bounds IDs may lead to crashes. Currently the
max channel check in the core gets skipped if driver can't fetch
the indirection table or when we can't allocate memory.
Both of those conditions should be extremely rare but if they do
happen we should try to be safe and fail the channel change.

Summary
In the Linux kernel, the following vulnerability has been resolved:
efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
The TPM event log table is a Linux specific construct, where the data
produced by the GetEventLog() boot service is cached in memory, and
passed on to the OS using an EFI configuration table.
The use of EFI_LOADER_DATA here results in the region being left
unreserved in the E820 memory map constructed by the EFI stub, and this
is the memory description that is passed on to the incoming kernel by
kexec, which is therefore unaware that the region should be reserved.
Even though the utility of the TPM2 event log after a kexec is
questionable, any corruption might send the parsing code off into the
weeds and crash the kernel. So let's use EFI_ACPI_RECLAIM_MEMORY
instead, which is always treated as reserved by the E820 conversion
logic.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos
In case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL
referencing a non-existing BTF type, function bpf_core_calc_relo_insn
would cause a null pointer deference.
Fix this by adding a proper check upper in call stack, as malformed
relocation records could be passed from user space.
Simplest reproducer is a program:
r0 = 0
exit
With a single relocation record:
.insn_off = 0, /* patch first instruction */
.type_id = 100500, /* this type id does not exist */
.access_str_off = 6, /* offset of string "0" */
.kind = BPF_CORE_TYPE_ID_LOCAL,
See the link for original reproducer or next commit for a test case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/iwcm: Fix WARNING:at_kernel/workqueue.c:#check_flush_dependency
In the commit aee2424246f9 ("RDMA/iwcm: Fix a use-after-free related to
destroying CM IDs"), the function flush_workqueue is invoked to flush the
work queue iwcm_wq.
But at that time, the work queue iwcm_wq was created via the function
alloc_ordered_workqueue without the flag WQ_MEM_RECLAIM.
Because the current process is trying to flush the whole iwcm_wq, if
iwcm_wq doesn't have the flag WQ_MEM_RECLAIM, verify that the current
process is not reclaiming memory or running on a workqueue which doesn't
have the flag WQ_MEM_RECLAIM as that can break forward-progress guarantee
leading to a deadlock.
The call trace is as below:

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: Fix null pointer dereference in trace
ucsi_register_altmode checks IS_ERR for the alt pointer and treats
NULL as valid. When CONFIG_TYPEC_DP_ALTMODE is not enabled,
ucsi_register_displayport returns NULL which causes a NULL pointer
dereference in trace. Rather than return NULL, call
typec_port_register_altmode to register DisplayPort alternate mode
as a non-controllable mode when CONFIG_TYPEC_DP_ALTMODE is not enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: Do not bring the device up after non-fatal error
Commit 004d25060c78 ("igb: Fix igb_down hung on surprise removal")
changed igb_io_error_detected() to ignore non-fatal pcie errors in order
to avoid hung task that can happen when igb_down() is called multiple
times. This caused an issue when processing transient non-fatal errors.
igb_io_resume(), which is called after igb_io_error_detected(), assumes
that device is brought down by igb_io_error_detected() if the interface
is up. This resulted in panic with stacktrace below.

To fix this issue igb_io_resume() checks if the interface is running and
the device is not down this means igb_io_error_detected() did not bring
the device down and there is no need to bring it up.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Initialize get_bytes_per_element's default to 1
Variables, used as denominators and maybe not assigned to other values,
should not be 0. bytes_per_element_y & bytes_per_element_c are
initialized by get_bytes_per_element() which should never return 0.
This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix index out of bounds in degamma hardware format translation
Fixes index out of bounds issue in
`cm_helper_translate_curve_to_degamma_hw_format` function. The issue
could occur when the index 'i' exceeds the number of transfer function
points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds the function returns
false to indicate an error.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max

Summary
In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix buffer overflow when parsing NFS reparse points
ReparseDataLength is sum of the InodeType size and DataBuffer size.
So to get DataBuffer size it is needed to subtract InodeType's size from
ReparseDataLength.
Function cifs_strndup_from_utf16() is currentlly accessing buf->DataBuffer
at position after the end of the buffer because it does not subtract
InodeType size from the length. Fix this problem and correctly subtract
variable len.
Member InodeType is present only when reparse buffer is large enough. Check
for ReparseDataLength before accessing InodeType to prevent another invalid
memory access.
Major and minor rdev values are present also only when reparse buffer is
large enough. Check for reparse buffer size before calling reparse_mkdev().

Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/smt: Fix unbalance sched_smt_present dec/inc
I got the following warn report while doing stress test:
jump label: negative count!
WARNING: CPU: 3 PID: 38 at kernel/jump_label.c:263 static_key_slow_try_dec+0x9d/0xb0
Call Trace:
<TASK>
__static_key_slow_dec_cpuslocked+0x16/0x70

</TASK>
Because when cpuset_cpu_inactive() fails in sched_cpu_deactivate(),
the cpu offline failed, but sched_smt_present is decremented before
calling sched_cpu_deactivate(), it leads to unbalanced dec/inc, so
fix it by incrementing sched_smt_present in the error path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for head_pipe in dcn32_acquire_idle_pipe_for_head_pipe_in_layer
This commit addresses a potential null pointer dereference issue in the
`dcn32_acquire_idle_pipe_for_head_pipe_in_layer` function. The issue
could occur when `head_pipe` is null.
The fix adds a check to ensure `head_pipe` is not null before asserting
it. If `head_pipe` is null, the function returns NULL to prevent a
potential null pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn32/dcn32_resource.c:2690 dcn32_acquire_idle_pipe_for_head_pipe_in_layer() error: we previously assumed 'head_pipe' could be null (see line 2681)

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSD: Limit the number of concurrent async COPY operations
Nothing appears to limit the number of concurrent async COPY
operations that clients can start. In addition, AFAICT each async
COPY can copy an unlimited number of 4MB chunks, so can run for a
long time. Thus IMO async COPY can become a DoS vector.
Add a restriction mechanism that bounds the number of concurrent
background COPY operations. Start simple and try to be fair -- this
patch implements a per-namespace limit.
An async COPY request that occurs while this limit is exceeded gets
NFS4ERR_DELAY. The requesting client can choose to send the request
again after a delay or fall back to a traditional read/write style
copy.
If there is need to make the mechanism more sophisticated, we can
visit that in future patches.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: wait for fixup workers before stopping cleaner kthread during umount
During unmount, at close_ctree(), we have the following steps in this order:
1) Park the cleaner kthread - this doesn't destroy the kthread, it basically
halts its execution (wake ups against it work but do nothing);
2) We stop the cleaner kthread - this results in freeing the respective
struct task_struct;
3) We call btrfs_stop_all_workers() which waits for any jobs running in all
the work queues and then free the work queues.
Syzbot reported a case where a fixup worker resulted in a crash when doing
a delayed iput on its inode while attempting to wake up the cleaner at
btrfs_add_delayed_iput(), because the task_struct of the cleaner kthread
was already freed. This can happen during unmount because we don't wait
for any fixup workers still running before we call kthread_stop() against
the cleaner kthread, which stops and free all its resources.
Fix this by waiting for any fixup workers at close_ctree() before we call
kthread_stop() against the cleaner and run pending delayed iputs.
The stack traces reported by syzbot were the following:

This can happen during unmount because we don\u0027t wait\nfor any fixup workers still running before we call kthread_stop() against\nthe cleaner kthread, which stops and free all its resources.\n\nFix this by waiting for any fixup workers at close_ctree() before we call\nkthread_stop() against the cleaner and run pending delayed iputs.\n\nThe stack traces reported by syzbot were the following:\n\n BUG: KASAN: slab-use-after-free in __lock_acquire+0x77/0x2050 kernel/locking/lockdep.c:5065\n Read of size 8 at addr ffff8880272a8a18 by task kworker/u8:3/52\n\n CPU: 1 UID: 0 PID: 52 Comm: kworker/u8:3 Not tainted 6.12.0-rc1-syzkaller #0\n Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 09/13/2024\n Workqueue: btrfs-fixup btrfs_work_helper\n Call Trace:\n \u003cTASK\u003e\n __dump_stack lib/dump_stack.c:94 [inline]\n dump_stack_lvl+0x241/0x360 lib/dump_stack.c:120\n print_address_description mm/kasan/report.c:377 [inline]\n print_report+0x169/0x550 mm/kasan/report.c:488\n kasan_report+0x143/0x180 mm/kasan/report.c:601\n __lock_acquire+0x77/0x2050 kernel/locking/lockdep.c:5065\n lock_acquire+0x1ed/0x550 kernel/locking/lockdep.c:5825\n __raw_spin_lock_irqsave include/linux/spinlock_api_smp.h:110 [inline]\n _raw_spin_lock_irqsave+0xd5/0x120 kernel/locking/spinlock.c:162\n class_raw_spinlock_irqsave_constructor include/linux/spinlock.h:551 [inline]\n try_to_wake_up+0xb0/0x1480 kernel/sched/core.c:4154\n btrfs_writepage_fixup_worker+0xc16/0xdf0 fs/btrfs/inode.c:2842\n btrfs_work_helper+0x390/0xc50 fs/btrfs/async-thread.c:314\n process_one_work kernel/workqueue.c:3229 [inline]\n process_scheduled_works+0xa63/0x1850 kernel/workqueue.c:3310\n worker_thread+0x870/0xd30 kernel/workqueue.c:3391\n kthread+0x2f0/0x390 kernel/kthread.c:389\n ret_from_fork+0x4b/0x80 arch/x86/kernel/process.c:147\n ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244\n \u003c/TASK\u003e\n\n Allocated by task 2:\n kasan_save_stack mm/kasan/common.c:47 [inline]\n kasan_save_track+0x3f/0x80 mm/kasan/common.c:68\n unpoison_slab_object mm/kasan/common.c:319 [inline]\n __kasan_slab_alloc+0x66/0x80 mm/kasan/common.c:345\n kasan_slab_alloc include/linux/kasan.h:247 [inline]\n slab_post_alloc_hook mm/slub.c:4086 [inline]\n slab_alloc_node mm/slub.c:4135 [inline]\n kmem_cache_alloc_node_noprof+0x16b/0x320 mm/slub.c:4187\n alloc_task_struct_node kernel/fork.c:180 [inline]\n dup_task_struct+0x57/0x8c0 kernel/fork.c:1107\n copy_process+0x5d1/0x3d50 kernel/fork.c:2206\n kernel_clone+0x223/0x880 kernel/fork.c:2787\n kernel_thread+0x1bc/0x240 kernel/fork.c:2849\n create_kthread kernel/kthread.c:412 [inline]\n kthreadd+0x60d/0x810 kernel/kthread.c:765\n ret_from_fork+0x4b/0x80 arch/x86/kernel/process.c:147\n ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244\n\n Freed by task 61:\n kasan_save_stack mm/kasan/common.c:47 [inline]\n kasan_save_track+0x3f/0x80 mm/kasan/common.c:68\n kasan_save_free_info+0x40/0x50 mm/kasan/generic.c:579\n poison_slab_object mm/kasan/common.c:247 [inline]\n __kasan_slab_free+0x59/0x70 mm/kasan/common.c:264\n kasan_slab_free include/linux/kasan.h:230 [inline]\n slab_free_h\n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix firmware crash due to invalid peer nss
Currently, if the access point receives an association
request containing an Extended HE Capabilities Information
Element with an invalid MCS-NSS, it triggers a firmware
crash.
This issue arises when EHT-PHY capabilities shows support
for a bandwidth and MCS-NSS set for that particular
bandwidth is filled by zeros and due to this, driver obtains
peer_nss as 0 and sending this value to firmware causes
crash.
Address this issue by implementing a validation step for
the peer_nss value before passing it to the firmware. If
the value is greater than zero, proceed with forwarding
it to the firmware. However, if the value is invalid,
reject the association request to prevent potential
firmware crashes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu: Fix buffer overflow in print_cpu_stall_info()
The rcuc-starvation output from print_cpu_stall_info() might overflow the
buffer if there is a huge difference in jiffies difference. The situation
might seem improbable, but computers sometimes get very confused about
time, which can result in full-sized integers, and, in this case,
buffer overflow.
Also, the unsigned jiffies difference is printed using %ld, which is
normally for signed integers. This is intentional for debugging purposes,
but it is not obvious from the code.
This commit therefore changes sprintf() to snprintf() and adds a
clarifying comment about intention of %ld format.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check link_res->hpo_dp_link_enc before using it
[WHAT & HOW]
Functions dp_enable_link_phy and dp_disable_link_phy can pass link_res
without initializing hpo_dp_link_enc and it is necessary to check for
null before dereferencing.
This fixes 2 FORWARD_NULL issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
PCI: kirin: Fix buffer overflow in kirin_pcie_parse_port()
Within kirin_pcie_parse_port(), the pcie->num_slots is compared to
pcie->gpio_id_reset size (MAX_PCI_SLOTS) which is correct and would lead
to an overflow.
Thus, fix condition to pcie->num_slots + 1 >= MAX_PCI_SLOTS and move
pcie->num_slots increment below the if-statement to avoid out-of-bounds
array access.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: dax: fix overflowing extents beyond inode size when partially writing
The dax_iomap_rw() does two things in each iteration: map written blocks
and copy user data to blocks. If the process is killed by user(See signal
handling in dax_iomap_iter()), the copied data will be returned and added
on inode size, which means that the length of written extents may exceed
the inode size, then fsck will fail. An example is given as:
dd if=/dev/urandom of=file bs=4M count=1
dax_iomap_rw
iomap_iter // round 1
ext4_iomap_begin
ext4_iomap_alloc // allocate 0~2M extents(written flag)
dax_iomap_iter // copy 2M data
iomap_iter // round 2
iomap_iter_advance
iter->pos += iter->processed // iter->pos = 2M
ext4_iomap_begin
ext4_iomap_alloc // allocate 2~4M extents(written flag)
dax_iomap_iter
fatal_signal_pending
done = iter->pos - iocb->ki_pos // done = 2M
ext4_handle_inode_extension
ext4_update_inode_size // inode size = 2M
fsck reports: Inode 13, i_size is 2097152, should be 4194304. Fix?
Fix the problem by truncating extents if the written length is smaller
than expected.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: move netif_queue_set_napi to rtnl-protected sections
Currently, netif_queue_set_napi() is called from ice_vsi_rebuild() that is
not rtnl-locked when called from the reset. This creates the need to take
the rtnl_lock just for a single function and complicates the
synchronization with .ndo_bpf. At the same time, there no actual need to
fill napi-to-queue information at this exact point.
Fill napi-to-queue information when opening the VSI and clear it when the
VSI is being closed. Those routines are already rtnl-locked.
Also, rewrite napi-to-queue assignment in a way that prevents inclusion of
XDP queues, as this leads to out-of-bounds writes, such as one below.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Remove SCSI host only if added
If host tries to remove ufshcd driver from a UFS device it would cause a
kernel panic if ufshcd_async_scan fails during ufshcd_probe_hba before
adding a SCSI host with scsi_add_host and MCQ is enabled since SCSI host
has been defered after MCQ configuration introduced by commit 0cab4023ec7b
("scsi: ufs: core: Defer adding host to SCSI if MCQ is supported").
To guarantee that SCSI host is removed only if it has been added, set the
scsi_host_added flag to true after adding a SCSI host and check whether it
is set or not before removing it.

======================================================================
If the size of the integer (unsigned n) is bigger than 32 in snto32(),
shift exponent will be too large for 32-bit type 'int', resulting in a
shift-out-of-bounds bug.
Fix this by adding a check on the size of the integer (unsigned n) in
snto32(). To add support for n greater than 32 bits, set n to 32, if n
is greater than 32.

Summary
In the Linux kernel, the following vulnerability has been resolved:
af_unix: Get user_ns from in_skb in unix_diag_get_exact().
Wei Chen reported a NULL deref in sk_user_ns() [0][1], and Paolo diagnosed
the root cause: in unix_diag_get_exact(), the newly allocated skb does not
have sk. [2]
We must get the user_ns from the NETLINK_CB(in_skb).sk and pass it to
sk_diag_fill().

Summary
In the Linux kernel, the following vulnerability has been resolved:
device-dax: correct pgoff align in dax_set_mapping()
pgoff should be aligned using ALIGN_DOWN() instead of ALIGN(). Otherwise,
vmf->address not aligned to fault_size will be aligned to the next
alignment, that can result in memory failure getting the wrong address.
It's a subtle situation that only can be observed in
page_mapped_in_vma() after the page is page fault handled by
dev_dax_huge_fault. Generally, there is little chance to perform
page_mapped_in_vma in dev-dax's page unless in specific error injection
to the dax device to trigger an MCE - memory-failure. In that case,
page_mapped_in_vma() will be triggered to determine which task is
accessing the failure address and kill that task in the end.
We used self-developed dax device (which is 2M aligned mapping) , to
perform error injection to random address. It turned out that error
injected to non-2M-aligned address was causing endless MCE until panic.
Because page_mapped_in_vma() kept resulting wrong address and the task
accessing the failure address was never killed properly:

It took us several weeks to pinpoint this problem, but we eventually
used bpftrace to trace the page fault and mce address and successfully
identified the issue.
Joao added:
; Likely we never reproduce in production because we always pin
: device-dax regions in the region align they provide (Qemu does
: similarly with prealloc in hugetlb/file backed memory). I think this
: bug requires that we touch *unpinned* device-dax regions unaligned to
: the device-dax selected alignment (page size i.e. 4K/2M/1G)

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix null-ptr-deref when journal load failed.
During the mounting process, if journal_reset() fails because of too short
journal, then lead to jbd2_journal_load() fails with NULL j_sb_buffer.
Subsequently, ocfs2_journal_shutdown() calls
jbd2_journal_flush()->jbd2_cleanup_journal_tail()->
__jbd2_update_log_tail()->jbd2_journal_update_sb_log_tail()
->lock_buffer(journal->j_sb_buffer), resulting in a null-pointer
dereference error.
To resolve this issue, we should check the JBD2_LOADED flag to ensure the
journal was properly loaded. Additionally, use journal instead of
osb->journal directly to simplify the code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix access to uninitialised lock in fc replay path
The following kernel trace can be triggered with fstest generic/629 when
executed against a filesystem with fast-commit feature enabled:
INFO: trying to register non-static key.
The code is fine but needs lockdep annotation, or maybe
you didn't initialize this object before use?
turning off the locking correctness validator.
CPU: 0 PID: 866 Comm: mount Not tainted 6.10.0+ #11
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.2-3-gd478f380-prebuilt.qemu.org 04/01/2014

In the replay path there's an attempt to lock sbi->s_bdev_wb_lock in
function ext4_check_bdev_write_error(). Unfortunately, at this point this
spinlock has not been initialized yet. Moving it's initialization to an
earlier point in __ext4_fill_super() fixes this splat.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_reject_ipv6: fix nf_reject_ip6_tcphdr_put()
syzbot reported that nf_reject_ip6_tcphdr_put() was possibly sending
garbage on the four reserved tcp bits (th->res1)
Use skb_put_zero() to clear the whole TCP header,
as done in nf_reject_ip_tcphdr_put()

Summary
In the Linux kernel, the following vulnerability has been resolved:
KEYS: prevent NULL pointer dereference in find_asymmetric_key()
In find_asymmetric_key(), if all NULLs are passed in the id_{0,1,2}
arguments, the kernel will first emit WARN but then have an oops
because id_2 gets dereferenced anyway.
Add the missing id_2 check and move WARN_ON() to the final else branch
to avoid duplicate NULL checks.
Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.

This issue arises because, upon closing the file descriptor (which happens
when we interrupt `kmscube`), the active performance monitor is not
stopped. Although all perfmons are destroyed in `v3d_perfmon_close_file()`,
the active performance monitor's pointer (`v3d->active_perfmon`) is still
retained.
If `kmscube` is run again, the driver will attempt to stop the active
performance monitor using the stale pointer in `v3d->active_perfmon`.
However, this pointer is no longer valid because the previous process has
already terminated, and all performance monitors associated with it have
been destroyed and freed.
To fix this, when the active performance monitor belongs to a given
process, explicitly stop it before destroying and freeing it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i3c: mipi-i3c-hci: Fix out of bounds access in hci_dma_irq_handler
Do not loop over ring headers in hci_dma_irq_handler() that are not
allocated and enabled in hci_dma_init(). Otherwise out of bounds access
will occur from rings->headers[i] access when i >= number of allocated
ring headers.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: ops: Fix bounds check for _sx controls
For _sx controls the semantics of the max field is not the usual one, max
is the number of steps rather than the maximum value. This means that our
check in snd_soc_put_volsw_sx() needs to just check against the maximum
value.

Summary
In the Linux kernel, the following vulnerability has been resolved:
aoe: fix the potential use-after-free problem in more places
For fixing CVE-2023-6270, f98364e92662 ("aoe: fix the potential
use-after-free problem in aoecmd_cfg_pkts") makes tx() calling dev_put()
instead of doing in aoecmd_cfg_pkts(). It avoids that the tx() runs
into use-after-free.
Then Nicolai Stange found more places in aoe have potential use-after-free
problem with tx(). e.g. revalidate(), aoecmd_ata_rw(), resend(), probe()
and aoecmd_cfg_rsp(). Those functions also use aoenet_xmit() to push
packet to tx queue. So they should also use dev_hold() to increase the
refcnt of skb->dev.
On the other hand, moving dev_put() to tx() causes that the refcnt of
skb->dev be reduced to a negative value, because corresponding
dev_hold() are not called in revalidate(), aoecmd_ata_rw(), resend(),
probe(), and aoecmd_cfg_rsp(). This patch fixed this issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommufd: Protect against overflow of ALIGN() during iova allocation
Userspace can supply an iova and uptr such that the target iova alignment
becomes really big and ALIGN() overflows which corrupts the selected area
range during allocation. CONFIG_IOMMUFD_TEST can detect this:

better idea overall. Huge automatic alignments can fragment and chew up
the available IOVA space without any reason.

Summary
In the Linux kernel, the following vulnerability has been resolved:
platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses
The panasonic laptop code in various places uses the SINF array with index
values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array
is big enough.
Not all panasonic laptops have this many SINF array entries, for example
the Toughbook CF-18 model only has 10 SINF array entries. So it only
supports the AC+DC brightness entries and mute.
Check that the SINF array has a minimum size which covers all AC+DC
brightness entries and refuse to load if the SINF array is smaller.
For higher SINF indexes hide the sysfs attributes when the SINF array
does not contain an entry for that attribute, avoiding show()/store()
accessing the array out of bounds and add bounds checking to the probe()
and resume() code accessing these.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md: Don't ignore suspended array in md_check_recovery()
mddev_suspend() never stop sync_thread, hence it doesn't make sense to
ignore suspended array in md_check_recovery(), which might cause
sync_thread can't be unregistered.
After commit f52f5c71f3d4 ("md: fix stopping sync thread"), following
hang can be triggered by test shell/integrity-caching.sh:
1) suspend the array:
raid_postsuspend
mddev_suspend
2) stop the array:
raid_dtr
md_stop
__md_stop_writes
stop_sync_thread
set_bit(MD_RECOVERY_INTR, &mddev->recovery);
md_wakeup_thread_directly(mddev->sync_thread);
wait_event(..., !test_bit(MD_RECOVERY_RUNNING, &mddev->recovery))
3) sync thread done:
md_do_sync
set_bit(MD_RECOVERY_DONE, &mddev->recovery);
md_wakeup_thread(mddev->thread);
4) daemon thread can't unregister sync thread:
md_check_recovery
if (mddev->suspended)
return; -> return directly
md_read_sync_thread
clear_bit(MD_RECOVERY_RUNNING, &mddev->recovery);
-> MD_RECOVERY_RUNNING can't be cleared, hence step 2 hang;
This problem is not just related to dm-raid, fix it by ignoring
suspended array in md_check_recovery(). And follow up patches will
improve dm-raid better to frozen sync thread during suspend.

Summary
In the Linux kernel, the following vulnerability has been resolved:
r8169: add tally counter fields added with RTL8125
RTL8125 added fields to the tally counter, what may result in the chip
dma'ing these new fields to unallocated memory. Therefore make sure
that the allocated memory area is big enough to hold all of the
tally counter values, even if we use only parts of it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
md/raid5: fix deadlock that raid5d() wait for itself to clear MD_SB_CHANGE_PENDING
Xiao reported that lvm2 test lvconvert-raid-takeover.sh can hang with
small possibility, the root cause is exactly the same as commit
bed9e27baf52 ("Revert "md/raid5: Wait for MD_SB_CHANGE_PENDING in raid5d"")
However, Dan reported another hang after that, and junxiao investigated
the problem and found out that this is caused by plugged bio can't issue
from raid5d().
Current implementation in raid5d() has a weird dependence:
1) md_check_recovery() from raid5d() must hold 'reconfig_mutex' to clear
MD_SB_CHANGE_PENDING;
2) raid5d() handles IO in a deadloop, until all IO are issued;
3) IO from raid5d() must wait for MD_SB_CHANGE_PENDING to be cleared;
This behaviour is introduce before v2.6, and for consequence, if other
context hold 'reconfig_mutex', and md_check_recovery() can't update
super_block, then raid5d() will waste one cpu 100% by the deadloop, until
'reconfig_mutex' is released.
Refer to the implementation from raid1 and raid10, fix this problem by
skipping issue IO if MD_SB_CHANGE_PENDING is still set after
md_check_recovery(), daemon thread will be woken up when 'reconfig_mutex'
is released. Meanwhile, the hang problem will be fixed as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fuse: Initialize beyond-EOF page contents before setting uptodate
fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

Summary
In the Linux kernel, the following vulnerability has been resolved:
cachefiles: fix dentry leak in cachefiles_open_file()
A dentry leak may be caused when a lookup cookie and a cull are concurrent:
P1 | P2
-----------------------------------------------------------
cachefiles_lookup_cookie
cachefiles_look_up_object
lookup_one_positive_unlocked
// get dentry
cachefiles_cull
inode->i_flags |= S_KERNEL_FILE;
cachefiles_open_file
cachefiles_mark_inode_in_use
__cachefiles_mark_inode_in_use
can_use = false
if (!(inode->i_flags & S_KERNEL_FILE))
can_use = true
return false
return false
// Returns an error but doesn't put dentry
After that the following WARNING will be triggered when the backend folder
is umounted:
==================================================================
BUG: Dentry 000000008ad87947{i=7a,n=Dx_1_1.img} still in use (1) [unmount of ext4 sda]

==================================================================
Whether cachefiles_open_file() returns true or false, the reference count
obtained by lookup_positive_unlocked() in cachefiles_look_up_object()
should be released.
Therefore release that reference count in cachefiles_look_up_object() to
fix the above issue and simplify the code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (coretemp) Check for null before removing sysfs attrs
If coretemp_add_core() gets an error then pdata->core_data[indx]
is already NULL and has been kfreed. Don't pass that to
sysfs_remove_group() as that will crash in sysfs_remove_group().
[Shortened for readability]

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/9p: Fix a potential socket leak in p9_socket_open
Both p9_fd_create_tcp() and p9_fd_create_unix() will call
p9_socket_open(). If the creation of p9_trans_fd fails,
p9_fd_create_tcp() and p9_fd_create_unix() will return an
error directly instead of releasing the cscoket, which will
result in a socket leak.
This patch adds sock_release() to fix the leak issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: do not accept ACK of bytes we never sent
This patch is based on a detailed report and ideas from Yepeng Pan
and Christian Rossow.
ACK seq validation is currently following RFC 5961 5.2 guidelines:
The ACK value is considered acceptable only if
it is in the range of ((SND.UNA - MAX.SND.WND) <= SEG.ACK <=
SND.NXT). All incoming segments whose ACK value doesn't satisfy the
above condition MUST be discarded and an ACK sent back. It needs to
be noted that RFC 793 on page 72 (fifth check) says: "If the ACK is a
duplicate (SEG.ACK < SND.UNA), it can be ignored. If the ACK
acknowledges something not yet sent (SEG.ACK > SND.NXT) then send an
ACK, drop the segment, and return". The "ignored" above implies that
the processing of the incoming data segment continues, which means
the ACK value is treated as acceptable. This mitigation makes the
ACK check more stringent since any ACK < SND.UNA wouldn't be
accepted, instead only ACKs that are in the range ((SND.UNA -
MAX.SND.WND) <= SEG.ACK <= SND.NXT) get through.
This can be refined for new (and possibly spoofed) flows,
by not accepting ACK for bytes that were never sent.
This greatly improves TCP security at a little cost.
I added a Fixes: tag to make sure this patch will reach stable trees,
even if the 'blamed' patch was adhering to the RFC.
tp->bytes_acked was added in linux-4.2
Following packetdrill test (courtesy of Yepeng Pan) shows
the issue at hand:
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
+0 bind(3, ..., ...) = 0
+0 listen(3, 1024) = 0
// ---------------- Handshake ------------------- //
// when window scale is set to 14 the window size can be extended to
// 65535 * (2^14) = 1073725440. Linux would accept an ACK packet
// with ack number in (Server_ISN+1-1073725440. Server_ISN+1)
// ,though this ack number acknowledges some data never
// sent by the server.
+0 < S 0:0(0) win 65535 <mss 1400,nop,wscale 14>
+0 > S. 0:0(0) ack 1 <...>
+0 < . 1:1(0) ack 1 win 65535
+0 accept(3, ..., ...) = 4
// For the established connection, we send an ACK packet,
// the ack packet uses ack number 1 - 1073725300 + 2^32,
// where 2^32 is used to wrap around.
// Note: we used 1073725300 instead of 1073725440 to avoid possible
// edge cases.
// 1 - 1073725300 + 2^32 = 3221241997
// Oops, old kernels happily accept this packet.
+0 < . 1:1001(1000) ack 3221241997 win 65535
// After the kernel fix the following will be replaced by a challenge ACK,
// and prior malicious frame would be dropped.
+0 > . 1:1(0) ack 1001

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fail verification for sign-extension of packet data/data_end/data_meta
syzbot reported a kernel crash due to
commit 1f1e864b6555 ("bpf: Handle sign-extenstin ctx member accesses").
The reason is due to sign-extension of 32-bit load for
packet data/data_end/data_meta uapi field.
The original code looks like:
r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */
r3 = *(u32 *)(r1 + 80) /* load __sk_buff->data_end */
r0 = r2
r0 += 8
if r3 > r0 goto +1
...
Note that __sk_buff->data load has 32-bit sign extension.
After verification and convert_ctx_accesses(), the final asm code looks like:
r2 = *(u64 *)(r1 +208)
r2 = (s32)r2
r3 = *(u64 *)(r1 +80)
r0 = r2
r0 += 8
if r3 > r0 goto pc+1
...
Note that 'r2 = (s32)r2' may make the kernel __sk_buff->data address invalid
which may cause runtime failure.
Currently, in C code, typically we have
void *data = (void *)(long)skb->data;
void *data_end = (void *)(long)skb->data_end;
...
and it will generate
r2 = *(u64 *)(r1 +208)
r3 = *(u64 *)(r1 +80)
r0 = r2
r0 += 8
if r3 > r0 goto pc+1
If we allow sign-extension,
void *data = (void *)(long)(int)skb->data;
void *data_end = (void *)(long)skb->data_end;
...
the generated code looks like
r2 = *(u64 *)(r1 +208)
r2 <<= 32
r2 s>>= 32
r3 = *(u64 *)(r1 +80)
r0 = r2
r0 += 8
if r3 > r0 goto pc+1
and this will cause verification failure since "r2 <<= 32" is not allowed
as "r2" is a packet pointer.
To fix this issue for case
r2 = *(s32 *)(r1 + 76) /* load __sk_buff->data */
this patch added additional checking in is_valid_access() callback
function for packet data/data_end/data_meta access. If those accesses
are with sign-extenstion, the verification will fail.

Summary
In the Linux kernel, the following vulnerability has been resolved:
cxl/pci: Fix disabling memory if DVSEC CXL Range does not match a CFMWS window
The Linux CXL subsystem is built on the assumption that HPA == SPA.
That is, the host physical address (HPA) the HDM decoder registers are
programmed with are system physical addresses (SPA).
During HDM decoder setup, the DVSEC CXL range registers (cxl-3.1,
8.1.3.8) are checked if the memory is enabled and the CXL range is in
a HPA window that is described in a CFMWS structure of the CXL host
bridge (cxl-3.1, 9.18.1.3).
Now, if the HPA is not an SPA, the CXL range does not match a CFMWS
window and the CXL memory range will be disabled then. The HDM decoder
stops working which causes system memory being disabled and further a
system hang during HDM decoder initialization, typically when a CXL
enabled kernel boots.
Prevent a system hang and do not disable the HDM decoder if the
decoder's CXL range is not found in a CFMWS window.
Note the change only fixes a hardware hang, but does not implement
HPA/SPA translation. Support for this can be added in a follow on
patch series.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix race setting file private on concurrent lseek using same fd
When doing concurrent lseek(2) system calls against the same file
descriptor, using multiple threads belonging to the same process, we have
a short time window where a race happens and can result in a memory leak.
The race happens like this:
1) A program opens a file descriptor for a file and then spawns two
threads (with the pthreads library for example), lets call them
task A and task B;
2) Task A calls lseek with SEEK_DATA or SEEK_HOLE and ends up at
file.c:find_desired_extent() while holding a read lock on the inode;
3) At the start of find_desired_extent(), it extracts the file's
private_data pointer into a local variable named 'private', which has
a value of NULL;
4) Task B also calls lseek with SEEK_DATA or SEEK_HOLE, locks the inode
in shared mode and enters file.c:find_desired_extent(), where it also
extracts file->private_data into its local variable 'private', which
has a NULL value;
5) Because it saw a NULL file private, task A allocates a private
structure and assigns to the file structure;
6) Task B also saw a NULL file private so it also allocates its own file
private and then assigns it to the same file structure, since both
tasks are using the same file descriptor.
At this point we leak the private structure allocated by task A.
Besides the memory leak, there's also the detail that both tasks end up
using the same cached state record in the private structure (struct
btrfs_file_private::llseek_cached_state), which can result in a
use-after-free problem since one task can free it while the other is
still using it (only one task took a reference count on it). Also, sharing
the cached state is not a good idea since it could result in incorrect
results in the future - right now it should not be a problem because it
end ups being used only in extent-io-tree.c:count_range_bits() where we do
range validation before using the cached state.
Fix this by protecting the private assignment and check of a file while
holding the inode's spinlock and keep track of the task that allocated
the private, so that it's used only by that task in order to prevent
user-after-free issues with the cached state record as well as potentially
using it incorrectly in the future.

Also, sharing\nthe cached state is not a good idea since it could result in incorrect\nresults in the future - right now it should not be a problem because it\nend ups being used only in extent-io-tree.c:count_range_bits() where we do\nrange validation before using the cached state.\n\nFix this by protecting the private assignment and check of a file while\nholding the inode\u0027s spinlock and keep track of the task that allocated\nthe private, so that it\u0027s used only by that task in order to prevent\nuser-after-free issues with the cached state record as well as potentially\nusing it incorrectly in the future."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rtrs-clt: Reset cid to con_num - 1 to stay in bounds
In the function init_conns(), after the create_con() and create_cm() for
loop if something fails. In the cleanup for loop after the destroy tag, we
access out of bound memory because cid is set to clt_path->s.con_num.
This commits resets the cid to clt_path->s.con_num - 1, to stay in bounds
in the cleanup loop later.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix improper handling of refcount in ice_dpll_init_rclk_pins()
This patch addresses a reference count handling issue in the
ice_dpll_init_rclk_pins() function. The function calls ice_dpll_get_pins(),
which increments the reference count of the relevant resources. However,
if the condition WARN_ON((!vsi || !vsi->netdev)) is met, the function
currently returns an error without properly releasing the resources
acquired by ice_dpll_get_pins(), leading to a reference count leak.
To resolve this, the check has been moved to the top of the function. This
ensures that the function verifies the state before any resources are
acquired, avoiding the need for additional resource management in the
error path.
This bug was identified by an experimental static analysis tool developed
by our team. The tool specializes in analyzing reference count operations
and detecting potential issues where resources are not properly managed.
In this case, the tool flagged the missing release operation as a
potential problem, which led to the development of this patch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Handle mailbox timeouts in lpfc_get_sfp_info
The MBX_TIMEOUT return code is not handled in lpfc_get_sfp_info and the
routine unconditionally frees submitted mailbox commands regardless of
return status. The issue is that for MBX_TIMEOUT cases, when firmware
returns SFP information at a later time, that same mailbox memory region
references previously freed memory in its cmpl routine.
Fix by adding checks for the MBX_TIMEOUT return code. During mailbox
resource cleanup, check the mbox flag to make sure that the wait did not
timeout. If the MBOX_WAKE flag is not set, then do not free the resources
because it will be freed when firmware completes the mailbox at a later
time in its cmpl routine.
Also, increase the timeout from 30 to 60 seconds to accommodate boot
scripts requiring longer timeouts.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme: fix SRCU protection of nvme_ns_head list
Walking the nvme_ns_head siblings list is protected by the head's srcu
in nvme_ns_head_submit_bio() but not nvme_mpath_revalidate_paths().
Removing namespaces from the list also fails to synchronize the srcu.
Concurrent scan work can therefore cause use-after-frees.
Hold the head's srcu lock in nvme_mpath_revalidate_paths() and
synchronize with the srcu, not the global RCU, in nvme_ns_remove().
Observed the following panic when making NVMe/RDMA connections
with native multipath on the Rocky Linux 8.6 kernel
(it seems the upstream kernel has the same race condition).
Disassembly shows the faulting instruction is cmp 0x50(%rdx),%rcx;
computing capacity != get_capacity(ns->disk).
Address 0x50 is dereferenced because ns->disk is NULL.
The NULL disk appears to be the result of concurrent scan work
freeing the namespace (note the log line in the middle of the panic).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate()
The psc->div[] array has psc->num_div elements. These values come from
when we call clk_hw_register_div(). It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >=
instead of > to prevent an out of bounds read.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv4: Handle attempt to delete multipath route when fib_info contains an nh reference
Gwangun Jung reported a slab-out-of-bounds access in fib_nh_match:
fib_nh_match+0xf98/0x1130 linux-6.0-rc7/net/ipv4/fib_semantics.c:961
fib_table_delete+0x5f3/0xa40 linux-6.0-rc7/net/ipv4/fib_trie.c:1753
inet_rtm_delroute+0x2b3/0x380 linux-6.0-rc7/net/ipv4/fib_frontend.c:874
Separate nexthop objects are mutually exclusive with the legacy
multipath spec. Fix fib_nh_match to return if the config for the
to be deleted route contains a multipath spec while the fib_info
is using a nexthop object.

Summary
In the Linux kernel, the following vulnerability has been resolved:
memcg: fix possible use-after-free in memcg_write_event_control()
memcg_write_event_control() accesses the dentry->d_name of the specified
control fd to route the write call. As a cgroup interface file can't be
renamed, it's safe to access d_name as long as the specified file is a
regular cgroup file. Also, as these cgroup interface files can't be
removed before the directory, it's safe to access the parent too.
Prior to 347c4a874710 ("memcg: remove cgroup_event->cft"), there was a
call to __file_cft() which verified that the specified file is a regular
cgroupfs file before further accesses. The cftype pointer returned from
__file_cft() was no longer necessary and the commit inadvertently dropped
the file type check with it allowing any file to slip through. With the
invarients broken, the d_name and parent accesses can now race against
renames and removals of arbitrary files and cause use-after-free's.
Fix the bug by resurrecting the file type check in __file_cft(). Now that
cgroupfs is implemented through kernfs, checking the file operations needs
to go through a layer of indirection. Instead, let's check the superblock
and dentry type.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Add netif_device_attach/detach into PF reset flow
Ethtool callbacks can be executed while reset is in progress and try to
access deleted resources, e.g. getting coalesce settings can result in a
NULL pointer dereference seen below.
Reproduction steps:
Once the driver is fully initialized, trigger reset:
# echo 1 > /sys/class/net/<interface>/device/reset
when reset is in progress try to get coalesce settings using ethtool:
# ethtool -c <interface>
BUG: kernel NULL pointer dereference, address: 0000000000000020

RIP: 0033:0x7faee60d8e27
Calling netif_device_detach() before reset makes the net core not call
the driver when ethtool command is issued, the attempt to execute an
ethtool command during reset will result in the following message:
netlink error: No such device
instead of NULL pointer dereference. Once reset is done and
ice_rebuild() is executing, the netif_device_attach() is called to allow
for ethtool operations to occur again in a safe manner.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tpm: Clean up TPM space after command failure
tpm_dev_transmit prepares the TPM space before attempting command
transmission. However if the command fails no rollback of this
preparation is done. This can result in transient handles being leaked
if the device is subsequently closed with no further commands performed.
Fix this by flushing the space in the event of command transmission
failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFSv4: Prevent NULL-pointer dereference in nfs42_complete_copies()
On the node of an NFS client, some files saved in the mountpoint of the
NFS server were copied to another location of the same NFS server.
Accidentally, the nfs42_complete_copies() got a NULL-pointer dereference
crash with the following syslog:
[232064.838881] NFSv4: state recovery failed for open file nfs/pvc-12b5200d-cd0f-46a3-b9f0-af8f4fe0ef64.qcow2, error = -116

Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: check skb is non-NULL in tcp_rto_delta_us()
We have some machines running stock Ubuntu 20.04.6 which is their 5.4.0-174-generic
kernel that are running ceph and recently hit a null ptr dereference in
tcp_rearm_rto(). Initially hitting it from the TLP path, but then later we also
saw it getting hit from the RACK case as well. Here are examples of the oops
messages we saw in each of those cases:

Summary
In the Linux kernel, the following vulnerability has been resolved:
staging: iio: frequency: ad9834: Validate frequency parameter value
In ad9834_write_frequency() clk_get_rate() can return 0. In such case
ad9834_calc_freqreg() call will lead to division by zero. Checking
'if (fout > (clk_freq / 2))' doesn't protect in case of 'fout' is 0.
ad9834_write_frequency() is called from ad9834_write(), where fout is
taken from text buffer, which can contain any value.
Modify parameters checking.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)
This commit adds a null check for the 'afb' variable in the
amdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be
null at line 8388, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.
Changes since v1:
- Moved the null check for 'afb' to the line where 'afb' is used. (Alex)
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8433 amdgpu_dm_update_cursor()
error: we previously assumed 'afb' could be null (see line 8388)

Summary
In the Linux kernel, the following vulnerability has been resolved:
hwmon: (ibmpex) Fix possible UAF when ibmpex_register_bmc() fails
Smatch report warning as follows:
drivers/hwmon/ibmpex.c:509 ibmpex_register_bmc() warn:
'&data->list' not removed from list
If ibmpex_find_sensors() fails in ibmpex_register_bmc(), data will
be freed, but data->list will not be removed from driver_data.bmc_data,
then list traversal may cause UAF.
Fix by removeing it from driver_data.bmc_data before free().

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition
In the ether3_probe function, a timer is initialized with a callback
function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is
started, there is a risk of a race condition if the module or device
is removed, triggering the ether3_remove function to perform cleanup.
The sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| ether3_ledoff
ether3_remove |
free_netdev(dev); |
put_devic |
kfree(dev); |
| ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2);
| // use dev
Fix it by ensuring that the timer is canceled before proceeding with
the cleanup in ether3_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: kms: Add missing drm_crtc_commit_put
Commit 9ec03d7f1ed3 ("drm/vc4: kms: Wait on previous FIFO users before a
commit") introduced a global state for the HVS, with each FIFO storing
the current CRTC commit so that we can properly synchronize commits.
However, the refcounting was off and we thus ended up leaking the
drm_crtc_commit structure every commit. Add a drm_crtc_commit_put to
prevent the leakage.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: aovid use-after-free in ext4_ext_insert_extent()
As Ojaswin mentioned in Link, in ext4_ext_insert_extent(), if the path is
reallocated in ext4_ext_create_new_leaf(), we'll use the stale path and
cause UAF. Below is a sample trace with dummy values:
ext4_ext_insert_extent
path = *ppath = 2000
ext4_ext_create_new_leaf(ppath)
ext4_find_extent(ppath)
path = *ppath = 2000
if (depth > path[0].p_maxdepth)
kfree(path = 2000);
*ppath = path = NULL;
path = kcalloc() = 3000
*ppath = 3000;
return path;
/* here path is still 2000, UAF! */
eh = path[depth].p_hdr

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del()
The kref_put() function will call nport->release if the refcount drops to
zero. The nport->release release function is _efc_nport_free() which frees
"nport". But then we dereference "nport" on the next line which is a use
after free. Re-order these lines to avoid the use after free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
uprobes: fix kernel info leak via "[uprobes]" vma
xol_add_vma() maps the uninitialized page allocated by __create_xol_area()
into userspace. On some architectures (x86) this memory is readable even
without VM_READ, VM_EXEC results in the same pgprot_t as VM_EXEC|VM_READ,
although this doesn't really matter, debugger can read this memory anyway.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i3c: master: cdns: Fix use after free vulnerability in cdns_i3c_master Driver Due to Race Condition
In the cdns_i3c_master_probe function, &master->hj_work is bound with
cdns_i3c_master_hj. And cdns_i3c_master_interrupt can call
cnds_i3c_master_demux_ibis function to start the work.
If we remove the module which will call cdns_i3c_master_remove to
make cleanup, it will free master->base through i3c_master_unregister
while the work mentioned above will be used. The sequence of operations
that may lead to a UAF bug is as follows:
CPU0 CPU1
| cdns_i3c_master_hj
cdns_i3c_master_remove |
i3c_master_unregister(&master->base) |
device_unregister(&master->dev) |
device_release |
//free master->base |
| i3c_master_do_daa(&master->base)
| //use master->base
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in cdns_i3c_master_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nbd: fix race between timeout and normal completion
If request timetout is handled by nbd_requeue_cmd(), normal completion
has to be stopped for avoiding to complete this requeued request, other
use-after-free can be triggered.
Fix the race by clearing NBD_CMD_INFLIGHT in nbd_requeue_cmd(), meantime
make sure that cmd->lock is grabbed for clearing the flag and the
requeue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: return -EINVAL when namelen is 0
When we have a corrupted main.sqlite in /var/lib/nfs/nfsdcld/, it may
result in namelen being 0, which will cause memdup_user() to return
ZERO_SIZE_PTR.
When we access the name.data that has been assigned the value of
ZERO_SIZE_PTR in nfs4_client_to_reclaim(), null pointer dereference is
triggered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: br_netfilter: fix panic with metadata_dst skb
Fix a kernel panic in the br_netfilter module when sending untagged
traffic via a VxLAN device.
This happens during the check for fragmentation in br_nf_dev_queue_xmit.
It is dependent on:
1) the br_netfilter module being loaded;
2) net.bridge.bridge-nf-call-iptables set to 1;
3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port;
4) untagged frames with size higher than the VxLAN MTU forwarded/flooded
When forwarding the untagged packet to the VxLAN bridge port, before
the netfilter hooks are called, br_handle_egress_vlan_tunnel is called and
changes the skb_dst to the tunnel dst. The tunnel_dst is a metadata type
of dst, i.e., skb_valid_dst(skb) is false, and metadata->dst.dev is NULL.
Then in the br_netfilter hooks, in br_nf_dev_queue_xmit, there's a check
for frames that needs to be fragmented: frames with higher MTU than the
VxLAN device end up calling br_nf_ip_fragment, which in turns call
ip_skb_dst_mtu.
The ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dst
with valid dst->dev, thus the crash.
This case was never supported in the first place, so drop the packet
instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointers before using them
[WHAT & HOW]
These pointers are null checked previously in the same function,
indicating they might be null as reported by Coverity. As a result,
they need to be checked when used again.
This fixes 3 FORWARD_NULL issue reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: ISO: Fix multiple init when debugfs is disabled
If bt_debugfs is not created successfully, which happens if either
CONFIG_DEBUG_FS or CONFIG_DEBUG_FS_ALLOW_ALL is unset, then iso_init()
returns early and does not set iso_inited to true. This means that a
subsequent call to iso_init() will result in duplicate calls to
proto_register(), bt_sock_register(), etc.
With CONFIG_LIST_HARDENED and CONFIG_BUG_ON_DATA_CORRUPTION enabled, the
duplicate call to proto_register() triggers this BUG():
list_add double add: new=ffffffffc0b280d0, prev=ffffffffbab56250,
next=ffffffffc0b280d0.
------------[ cut here ]------------

This change removes the early return. The check for iso_debugfs being
NULL was unnecessary, it is always NULL when iso_inited is false.

Summary
In the Linux kernel, the following vulnerability has been resolved:
static_call: Replace pointless WARN_ON() in static_call_module_notify()
static_call_module_notify() triggers a WARN_ON(), when memory allocation
fails in __static_call_add_module().
That's not really justified, because the failure case must be correctly
handled by the well known call chain and the error code is passed
through to the initiating userspace application.
A memory allocation fail is not a fatal problem, but the WARN_ON() takes
the machine out when panic_on_warn is set.
Replace it with a pr_warn().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: fix buffer overflow in elem comparison
For vendor elements, the code here assumes that 5 octets
are present without checking. Since the element itself is
already checked to fit, we only need to check the length.

Summary
In the Linux kernel, the following vulnerability has been resolved:
IB/core: Fix ib_cache_setup_one error flow cleanup
When ib_cache_update return an error, we exit ib_cache_setup_one
instantly with no proper cleanup, even though before this we had
already successfully done gid_table_setup_one, that results in
the kernel WARN below.
Do proper cleanup using gid_table_cleanup_one before returning
the err in order to fix the issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix not cleanup led when bt_init fails
bt_init() calls bt_leds_init() to register led, but if it fails later,
bt_leds_cleanup() is not called to unregister it.
This can cause panic if the argument "bluetooth-power" in text is freed
and then another led_trigger_register() tries to access it:
BUG: unable to handle page fault for address: ffffffffc06d3bc0
RIP: 0010:strcmp+0xc/0x30
Call Trace:

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/khugepaged: invoke MMU notifiers in shmem/file collapse paths
Any codepath that zaps page table entries must invoke MMU notifiers to
ensure that secondary MMUs (like KVM) don't keep accessing pages which
aren't mapped anymore. Secondary MMUs don't hold their own references to
pages that are mirrored over, so failing to notify them can lead to page
use-after-free.
I'm marking this as addressing an issue introduced in commit f3f0e1d2150b
("khugepaged: add support of collapse for tmpfs/shmem pages"), but most of
the security impact of this only came in commit 27e1f8273113 ("khugepaged:
enable collapse pmd for pte-mapped THP"), which actually omitted flushes
for the removal of present PTEs, not just for the removal of empty page
tables.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jfs: Fix uninit-value access of new_ea in ea_buffer
syzbot reports that lzo1x_1_do_compress is using uninit-value:
=====================================================
BUG: KMSAN: uninit-value in lzo1x_1_do_compress+0x19f9/0x2510 lib/lzo/lzo1x_compress.c:178
...
Uninit was stored to memory at:
ea_put fs/jfs/xattr.c:639 [inline]
...
Local variable ea_buf created at:
__jfs_setxattr+0x5d/0x1ae0 fs/jfs/xattr.c:662
__jfs_xattr_set+0xe6/0x1f0 fs/jfs/xattr.c:934
=====================================================
The reason is ea_buf->new_ea is not initialized properly.
Fix this by using memset to empty its content at the beginning
in ea_get().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param
In the `wilc_parse_join_bss_param` function, the TSF field of the `ies`
structure is accessed after the RCU read-side critical section is
unlocked. According to RCU usage rules, this is illegal. Reusing this
pointer can lead to unpredictable behavior, including accessing memory
that has been updated or causing use-after-free issues.
This possible bug was identified using a static analysis tool developed
by myself, specifically designed to detect RCU-related issues.
To address this, the TSF value is now stored in a local variable
`ies_tsf` before the RCU lock is released. The `param->tsf_lo` field is
then assigned using this local variable, ensuring that the TSF value is
safely accessed.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block, bfq: fix possible UAF for bfqq->bic with merge chain
1) initial state, three tasks:
Process 1 Process 2 Process 3
(BIC1) (BIC2) (BIC3)
| Λ | Λ | Λ
| | | | | |
V | V | V |
bfqq1 bfqq2 bfqq3
process ref: 1 1 1
2) bfqq1 merged to bfqq2:
Process 1 Process 2 Process 3
(BIC1) (BIC2) (BIC3)
| | | Λ
\--------------\| | |
V V |
bfqq1--------->bfqq2 bfqq3
process ref: 0 2 1
3) bfqq2 merged to bfqq3:
Process 1 Process 2 Process 3
(BIC1) (BIC2) (BIC3)
here -> Λ | |
\--------------\ \-------------\|
V V
bfqq1--------->bfqq2---------->bfqq3
process ref: 0 1 3
In this case, IO from Process 1 will get bfqq2 from BIC1 first, and then
get bfqq3 through merge chain, and finially handle IO by bfqq3.
Howerver, current code will think bfqq2 is owned by BIC1, like initial
state, and set bfqq2->bic to BIC1.
bfq_insert_request
-> by Process 1
bfqq = bfq_init_rq(rq)
bfqq = bfq_get_bfqq_handle_split
bfqq = bic_to_bfqq
-> get bfqq2 from BIC1
bfqq->ref++
rq->elv.priv[0] = bic
rq->elv.priv[1] = bfqq
if (bfqq_process_refs(bfqq) == 1)
bfqq->bic = bic
-> record BIC1 to bfqq2
__bfq_insert_request
new_bfqq = bfq_setup_cooperator
-> get bfqq3 from bfqq2->new_bfqq
bfqq_request_freed(bfqq)
new_bfqq->ref++
rq->elv.priv[1] = new_bfqq
-> handle IO by bfqq3
Fix the problem by checking bfqq is from merge chain fist. And this
might fix a following problem reported by our syzkaller(unreproducible):

Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel: Limit the period on Haswell
Running the ltp test cve-2015-3290 concurrently reports the following
warnings.
perfevents: irq loop stuck!

Thanks to Thomas Gleixner's analysis, the issue is caused by the low
initial period (1) of the frequency estimation algorithm, which triggers
the defects of the HW, specifically erratum HSW11 and HSW143. (For the
details, please refer https://lore.kernel.org/lkml/87plq9l5d2.ffs@tglx/)
The HSW11 requires a period larger than 100 for the INST_RETIRED.ALL
event, but the initial period in the freq mode is 1. The erratum is the
same as the BDM11, which has been supported in the kernel. A minimum
period of 128 is enforced as well on HSW.
HSW143 is regarding that the fixed counter 1 may overcount 32 with the
Hyper-Threading is enabled. However, based on the test, the hardware
has more issues than it tells. Besides the fixed counter 1, the message
'interrupt took too long' can be observed on any counter which was armed
with a period < 32 and two events expired in the same NMI. A minimum
period of 32 is enforced for the rest of the events.
The recommended workaround code of the HSW143 is not implemented.
Because it only addresses the issue for the fixed counter. It brings
extra overhead through extra MSR writing. No related overcounting issue
has been reported so far.

Summary
In the Linux kernel, the following vulnerability has been resolved:
padata: use integer wrap around to prevent deadlock on seq_nr overflow
When submitting more than 2^32 padata objects to padata_do_serial, the
current sorting implementation incorrectly sorts padata objects with
overflowed seq_nr, causing them to be placed before existing objects in
the reorder list. This leads to a deadlock in the serialization process
as padata_find_next cannot match padata->seq_nr and pd->processed
because the padata instance with overflowed seq_nr will be selected
next.
To fix this, we use an unsigned integer wrap around to correctly sort
padata objects in scenarios with integer overflow.

Summary
In the Linux kernel, the following vulnerability has been resolved:
arm64: tlb: Fix TLBI RANGE operand
KVM/arm64 relies on TLBI RANGE feature to flush TLBs when the dirty
pages are collected by VMM and the page table entries become write
protected during live migration. Unfortunately, the operand passed
to the TLBI RANGE instruction isn't correctly sorted out due to the
commit 117940aa6e5f ("KVM: arm64: Define kvm_tlb_flush_vmid_range()").
It leads to crash on the destination VM after live migration because
TLBs aren't flushed completely and some of the dirty pages are missed.
For example, I have a VM where 8GB memory is assigned, starting from
0x40000000 (1GB). Note that the host has 4KB as the base page size.
In the middile of migration, kvm_tlb_flush_vmid_range() is executed
to flush TLBs. It passes MAX_TLBI_RANGE_PAGES as the argument to
__kvm_tlb_flush_vmid_range() and __flush_s2_tlb_range_op(). SCALE#3
and NUM#31, corresponding to MAX_TLBI_RANGE_PAGES, isn't supported
by __TLBI_RANGE_NUM(). In this specific case, -1 has been returned
from __TLBI_RANGE_NUM() for SCALE#3/2/1/0 and rejected by the loop
in the __flush_tlb_range_op() until the variable @scale underflows
and becomes -9, 0xffff708000040000 is set as the operand. The operand
is wrong since it's sorted out by __TLBI_VADDR_RANGE() according to
invalid @scale and @num.
Fix it by extending __TLBI_RANGE_NUM() to support the combination of
SCALE#3 and NUM#31. With the changes, [-1 31] instead of [-1 30] can
be returned from the macro, meaning the TLBs for 0x200000 pages in the
above example can be flushed in one shoot with SCALE#3 and NUM#31. The
macro TLBI_RANGE_MASK is dropped since no one uses it any more. The
comments are also adjusted accordingly.

SCALE#3\nand NUM#31, corresponding to MAX_TLBI_RANGE_PAGES, isn\u0027t supported\nby __TLBI_RANGE_NUM(). In this specific case, -1 has been returned\nfrom __TLBI_RANGE_NUM() for SCALE#3/2/1/0 and rejected by the loop\nin the __flush_tlb_range_op() until the variable @scale underflows\nand becomes -9, 0xffff708000040000 is set as the operand. The operand\nis wrong since it\u0027s sorted out by __TLBI_VADDR_RANGE() according to\ninvalid @scale and @num.\n\nFix it by extending __TLBI_RANGE_NUM() to support the combination of\nSCALE#3 and NUM#31. With the changes, [-1 31] instead of [-1 30] can\nbe returned from the macro, meaning the TLBs for 0x200000 pages in the\nabove example can be flushed in one shoot with SCALE#3 and NUM#31. The\nmacro TLBI_RANGE_MASK is dropped since no one uses it any more. The\ncomments are also adjusted accordingly."

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix Use-After-Free of rsv_qp on HIP08
Currently rsv_qp is freed before ib_unregister_device() is called
on HIP08. During the time interval, users can still dereg MR and
rsv_qp will be used in this process, leading to a UAF. Move the
release of rsv_qp after calling ib_unregister_device() to fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Handle null 'stream_status' in 'planes_changed_for_existing_stream'
This commit adds a null check for 'stream_status' in the function
'planes_changed_for_existing_stream'. Previously, the code assumed
'stream_status' could be null, but did not handle the case where it was
actually null. This could lead to a null pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:3784 planes_changed_for_existing_stream() error: we previously assumed 'stream_status' could be null (see line 3774)

Summary
In the Linux kernel, the following vulnerability has been resolved:
jffs2: prevent xattr node from overflowing the eraseblock
Add a check to make sure that the requested xattr node size is no larger
than the eraseblock minus the cleanmarker.
Unlike the usual inode nodes, the xattr nodes aren't split into parts
and spread across multiple eraseblocks, which means that a xattr node
must not occupy more than one eraseblock. If the requested xattr value is
too large, the xattr node can spill onto the next eraseblock, overwriting
the nodes and causing errors such as:
jffs2: argh. node added in wrong place at 0x0000b050(2)
jffs2: nextblock 0x0000a000, expected at 0000b00c
jffs2: error: (823) do_verify_xattr_datum: node CRC failed at 0x01e050,
read=0xfc892c93, calc=0x000000
jffs2: notice: (823) jffs2_get_inode_nodes: Node header CRC failed
at 0x01e00c. {848f,2fc4,0fef511f,59a3d171}
jffs2: Node at 0x0000000c with length 0x00001044 would run over the
end of the erase block
jffs2: Perhaps the file system was created with the wrong erase size?
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x00000010: 0x1044 instead
This breaks the filesystem and can lead to KASAN crashes such as:
BUG: KASAN: slab-out-of-bounds in jffs2_sum_add_kvec+0x125e/0x15d0

Summary
In the Linux kernel, the following vulnerability has been resolved:
fix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE
copy_fd_bitmaps(new, old, count) is expected to copy the first
count/BITS_PER_LONG bits from old->full_fds_bits[] and fill
the rest with zeroes. What it does is copying enough words
(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.
That works fine, *if* all bits past the cutoff point are
clear. Otherwise we are risking garbage from the last word
we'd copied.
For most of the callers that is true - expand_fdtable() has
count equal to old->max_fds, so there's no open descriptors
past count, let alone fully occupied words in ->open_fds[],
which is what bits in ->full_fds_bits[] correspond to.
The other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),
which is the smallest multiple of BITS_PER_LONG that covers all
opened descriptors below max_fds. In the common case (copying on
fork()) max_fds is ~0U, so all opened descriptors will be below
it and we are fine, by the same reasons why the call in expand_fdtable()
is safe.
Unfortunately, there is a case where max_fds is less than that
and where we might, indeed, end up with junk in ->full_fds_bits[] -
close_range(from, to, CLOSE_RANGE_UNSHARE) with
* descriptor table being currently shared
* 'to' being above the current capacity of descriptor table
* 'from' being just under some chunk of opened descriptors.
In that case we end up with observably wrong behaviour - e.g. spawn
a child with CLONE_FILES, get all descriptors in range 0..127 open,
then close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending
up with descriptor #128, despite #64 being observably not open.
The minimally invasive fix would be to deal with that in dup_fd().
If this proves to add measurable overhead, we can go that way, but
let's try to fix copy_fd_bitmaps() first.
* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).
* make copy_fd_bitmaps() take the bitmap size in words, rather than
bits; it's 'count' argument is always a multiple of BITS_PER_LONG,
so we are not losing any information, and that way we can use the
same helper for all three bitmaps - compiler will see that count
is a multiple of BITS_PER_LONG for the large ones, so it'll generate
plain memcpy()+memset().

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfix bitmap corruption on close_range() with CLOSE_RANGE_UNSHARE\n\ncopy_fd_bitmaps(new, old, count) is expected to copy the first\ncount/BITS_PER_LONG bits from old-\u003efull_fds_bits[] and fill\nthe rest with zeroes. What it does is copying enough words\n(BITS_TO_LONGS(count/BITS_PER_LONG)), then memsets the rest.\nThat works fine, *if* all bits past the cutoff point are\nclear. Otherwise we are risking garbage from the last word\nwe\u0027d copied.\n\nFor most of the callers that is true - expand_fdtable() has\ncount equal to old-\u003emax_fds, so there\u0027s no open descriptors\npast count, let alone fully occupied words in -\u003eopen_fds[],\nwhich is what bits in -\u003efull_fds_bits[] correspond to.\n\nThe other caller (dup_fd()) passes sane_fdtable_size(old_fdt, max_fds),\nwhich is the smallest multiple of BITS_PER_LONG that covers all\nopened descriptors below max_fds. In the common case (copying on\nfork()) max_fds is ~0U, so all opened descriptors will be below\nit and we are fine, by the same reasons why the call in expand_fdtable()\nis safe.\n\nUnfortunately, there is a case where max_fds is less than that\nand where we might, indeed, end up with junk in -\u003efull_fds_bits[] -\nclose_range(from, to, CLOSE_RANGE_UNSHARE) with\n\t* descriptor table being currently shared\n\t* \u0027to\u0027 being above the current capacity of descriptor table\n\t* \u0027from\u0027 being just under some chunk of opened descriptors.\nIn that case we end up with observably wrong behaviour - e.g. spawn\na child with CLONE_FILES, get all descriptors in range 0..127 open,\nthen close_range(64, ~0U, CLOSE_RANGE_UNSHARE) and watch dup(0) ending\nup with descriptor #128, despite #64 being observably not open.\n\nThe minimally invasive fix would be to deal with that in dup_fd().\nIf this proves to add measurable overhead, we can go that way, but\nlet\u0027s try to fix copy_fd_bitmaps() first.\n\n* new helper: bitmap_copy_and_expand(to, from, bits_to_copy, size).\n* make copy_fd_bitmaps() take the bitmap size in words, rather than\nbits; it\u0027s \u0027count\u0027 argument is always a multiple of BITS_PER_LONG,\nso we are not losing any information, and that way we can use the\nsame helper for all three bitmaps - compiler will see that count\nis a multiple of BITS_PER_LONG for the large ones, so it\u0027ll generate\nplain memcpy()+memset().\n\nReproducer added to tools/testing/selftests/core/close_range_test.c"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ppp: do not assume bh is held in ppp_channel_bridge_input()
Networking receive path is usually handled from BH handler.
However, some protocols need to acquire the socket lock, and
packets might be stored in the socket backlog is the socket was
owned by a user process.
In this case, release_sock(), __release_sock(), and sk_backlog_rcv()
might call the sk->sk_backlog_rcv() handler in process context.
sybot caught ppp was not considering this case in
ppp_channel_bridge_input() :

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: lpfc: Validate hdwq pointers before dereferencing in reset/errata paths
When the HBA is undergoing a reset or is handling an errata event, NULL ptr
dereference crashes may occur in routines such as
lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or
lpfc_abort_handler().
Add NULL ptr checks before dereferencing hdwq pointers that may have been
freed due to operations colliding with a reset or errata event handler.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fbcon: Fix a NULL pointer dereference issue in fbcon_putcs
syzbot has found a NULL pointer dereference bug in fbcon.
Here is the simplified C reproducer:
struct param {
uint8_t type;
struct tiocl_selection ts;
};
int main()
{
struct fb_con2fbmap con2fb;
struct param param;
int fd = open("/dev/fb1", 0, 0);
con2fb.console = 0x19;
con2fb.framebuffer = 0;
ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb);
param.type = 2;
param.ts.xs = 0; param.ts.ys = 0;
param.ts.xe = 0; param.ts.ye = 0;
param.ts.sel_mode = 0;
int fd1 = open("/dev/tty1", O_RDWR, 0);
ioctl(fd1, TIOCLINUX, ¶m);
con2fb.console = 1;
con2fb.framebuffer = 0;
ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb);
return 0;
}
After calling ioctl(fd1, TIOCLINUX, ¶m), the subsequent ioctl(fd, FBIOPUT_CON2FBMAP, &con2fb)
causes the kernel to follow a different execution path:
set_con2fb_map
-> con2fb_init_display
-> fbcon_set_disp
-> redraw_screen
-> hide_cursor
-> clear_selection
-> highlight
-> invert_screen
-> do_update_region
-> fbcon_putcs
-> ops->putcs
Since ops->putcs is a NULL pointer, this leads to a kernel panic.
To prevent this, we need to call set_blitting_type() within set_con2fb_map()
to properly initialize ops->putcs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix error path in multi-packet WQE transmit
Remove the erroneous unmap in case no DMA mapping was established
The multi-packet WQE transmit code attempts to obtain a DMA mapping for
the skb. This could fail, e.g. under memory pressure, when the IOMMU
driver just can't allocate more memory for page tables. While the code
tries to handle this in the path below the err_unmap label it erroneously
unmaps one entry from the sq's FIFO list of active mappings. Since the
current map attempt failed this unmap is removing some random DMA mapping
that might still be required. If the PCI function now presents that IOVA,
the IOMMU may assumes a rogue DMA access and e.g. on s390 puts the PCI
function in error state.
The erroneous behavior was seen in a stress-test environment that created
memory pressure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nfsd: call cache_put if xdr_reserve_space returns NULL
If not enough buffer space available, but idmap_lookup has triggered
lookup_fn which calls cache_get and returns successfully. Then we
missed to call cache_put here which pairs with cache_get.

Summary
In the Linux kernel, the following vulnerability has been resolved:
netem: fix return value if duplicate enqueue fails
There is a bug in netem_enqueue() introduced by
commit 5845f706388a ("net: netem: fix skb length BUG_ON in __skb_to_sgvec")
that can lead to a use-after-free.
This commit made netem_enqueue() always return NET_XMIT_SUCCESS
when a packet is duplicated, which can cause the parent qdisc's q.qlen
to be mistakenly incremented. When this happens qlen_notify() may be
skipped on the parent during destruction, leaving a dangling pointer
for some classful qdiscs like DRR.
There are two ways for the bug happen:
- If the duplicated packet is dropped by rootq->enqueue() and then
the original packet is also dropped.
- If rootq->enqueue() sends the duplicated packet to a different qdisc
and the original packet is dropped.
In both cases NET_XMIT_SUCCESS is returned even though no packets
are enqueued at the netem qdisc.
The fix is to defer the enqueue of the duplicate packet until after
the original packet has been guaranteed to return NET_XMIT_SUCCESS.

Summary
In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: avoid off-by-one read from userspace
We try to access count + 1 byte from userspace with memdup_user(buffer,
count + 1). However, the userspace only provides buffer of count bytes and
only these count bytes are verified to be okay to access. To ensure the
copied buffer is NUL terminated, we use memdup_user_nul instead.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: don't wait for tx queues if firmware is dead
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.
Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: stm32f7: Do not prepare/unprepare clock during runtime suspend/resume
In case there is any sort of clock controller attached to this I2C bus
controller, for example Versaclock or even an AIC32x4 I2C codec, then
an I2C transfer triggered from the clock controller clk_ops .prepare
callback may trigger a deadlock on drivers/clk/clk.c prepare_lock mutex.
This is because the clock controller first grabs the prepare_lock mutex
and then performs the prepare operation, including its I2C access. The
I2C access resumes this I2C bus controller via .runtime_resume callback,
which calls clk_prepare_enable(), which attempts to grab the prepare_lock
mutex again and deadlocks.
Since the clock are already prepared since probe() and unprepared in
remove(), use simple clk_enable()/clk_disable() calls to enable and
disable the clock on runtime suspend and resume, to avoid hitting the
prepare_lock mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost_vdpa: assign irq bypass producer token correctly
We used to call irq_bypass_unregister_producer() in
vhost_vdpa_setup_vq_irq() which is problematic as we don't know if the
token pointer is still valid or not.
Actually, we use the eventfd_ctx as the token so the life cycle of the
token should be bound to the VHOST_SET_VRING_CALL instead of
vhost_vdpa_setup_vq_irq() which could be called by set_status().
Fixing this by setting up irq bypass producer's token when handling
VHOST_SET_VRING_CALL and un-registering the producer before calling
vhost_vring_ioctl() to prevent a possible use after free as eventfd
could have been released in vhost_vring_ioctl(). And such registering
and unregistering will only be done if DRIVER_OK is set.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: use IWL_FW_CHECK for link ID check
The lookup function iwl_mvm_rcu_fw_link_id_to_link_conf() is
normally called with input from the firmware, so it should use
IWL_FW_CHECK() instead of WARN_ON().

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-dv-timings.c: fix too strict blanking sanity checks
Sanity checks were added to verify the v4l2_bt_timings blanking fields
in order to avoid integer overflows when userspace passes weird values.
But that assumed that userspace would correctly fill in the front porch,
backporch and sync values, but sometimes all you know is the total
blanking, which is then assigned to just one of these fields.
And that can fail with these checks.
So instead set a maximum for the total horizontal and vertical
blanking and check that each field remains below that.
That is still sufficient to avoid integer overflows, but it also
allows for more flexibility in how userspace fills in these fields.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error
Ensure index in rtl2832_pid_filter does not exceed 31 to prevent
out-of-bounds access.
dev->filters is a 32-bit value, so set_bit and clear_bit functions should
only operate on indices from 0 to 31. If index is 32, it will attempt to
access a non-existent 33rd bit, leading to out-of-bounds access.
Change the boundary check from index > 32 to index >= 32 to resolve this
issue.
[hverkuil: added fixes tag, rtl2830_pid_filter -> rtl2832_pid_filter in logmsg]

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: iaa - Fix potential use after free bug
The free_device_compression_mode(iaa_device, device_mode) function frees
"device_mode" but it iss passed to iaa_compression_modes[i]->free() a few
lines later resulting in a use after free.
The good news is that, so far as I can tell, nothing implements the
->free() function and the use after free happens in dead code. But, with
this fix, when something does implement it, we'll be ready. :)

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: always wait for both firmware loading attempts
In 'rtw_wait_firmware_completion()', always wait for both (regular and
wowlan) firmware loading attempts. Otherwise if 'rtw_usb_intf_init()'
has failed in 'rtw_usb_probe()', 'rtw_usb_disconnect()' may issue
'ieee80211_free_hw()' when one of 'rtw_load_firmware_cb()' (usually
the wowlan one) is still in progress, causing UAF detected by KASAN.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for set_output_gamma in dcn30_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the dcn30_set_output_transfer_func function. Previously,
set_output_gamma was being checked for nullity at line 386, but then it
was being dereferenced without any nullity check at line 401. This
could potentially lead to a null pointer dereference error if
set_output_gamma is indeed null.
To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a nullity check for
set_output_gamma before the call to set_output_gamma at line 401. If
set_output_gamma is null, we log an error message and do not call the
function.
This fix prevents a potential null pointer dereference error.

Previously,\nset_output_gamma was being checked for nullity at line 386, but then it\nwas being dereferenced without any nullity check at line 401. This\ncould potentially lead to a null pointer dereference error if\nset_output_gamma is indeed null.\n\nTo fix this, we now ensure that set_output_gamma is not null before\ndereferencing it. We do this by adding a nullity check for\nset_output_gamma before the call to set_output_gamma at line 401. If\nset_output_gamma is null, we log an error message and do not call the\nfunction.\n\nThis fix prevents a potential null pointer dereference error.\n\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:401 dcn30_set_output_transfer_func()\nerror: we previously assumed \u0027mpc-\u003efuncs-\u003eset_output_gamma\u0027 could be null (see line 386)\n\ndrivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c\n 373 bool dcn30_set_output_transfer_func(struct dc *dc,\n 374 struct pipe_ctx *pipe_ctx,\n 375 const struct dc_stream_state *stream)\n 376 {\n 377 int mpcc_id = pipe_ctx-\u003eplane_res.hubp-\u003einst;\n 378 struct mpc *mpc = pipe_ctx-\u003estream_res.opp-\u003ectx-\u003edc-\u003eres_pool-\u003empc;\n 379 const struct pwl_params *params = NULL;\n 380 bool ret = false;\n 381\n 382 /* program OGAM or 3DLUT only for the top pipe*/\n 383 if (pipe_ctx-\u003etop_pipe == NULL) {\n 384 /*program rmu shaper and 3dlut in MPC*/\n 385 ret = dcn30_set_mpc_shaper_3dlut(pipe_ctx, stream);\n 386 if (ret == false \u0026\u0026 mpc-\u003efuncs-\u003eset_output_gamma) {\n ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ If this is NULL\n\n 387 if (stream-\u003eout_transfer_func.type == TF_TYPE_HWPWL)\n 388 params = \u0026stream-\u003eout_transfer_func.pwl;\n 389 else if (pipe_ctx-\u003estream-\u003eout_transfer_func.type ==\n 390 TF_TYPE_DISTRIBUTED_POINTS \u0026\u0026\n 391 cm3_helper_translate_curve_to_hw_format(\n 392 \u0026stream-\u003eout_transfer_func,\n 393 \u0026mpc-\u003eblender_params, false))\n 394 params = \u0026mpc-\u003eblender_params;\n 395 /* there are no ROM LUTs in OUTGAM */\n 396 if (stream-\u003eout_transfer_func.type == TF_TYPE_PREDEFINED)\n 397 BREAK_TO_DEBUGGER();\n 398 }\n 399 }\n 400\n--\u003e 401 mpc-\u003efuncs-\u003eset_output_gamma(mpc, mpcc_id, params);\n ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Then it will crash\n\n 402 return ret;\n 403 }"

Summary
In the Linux kernel, the following vulnerability has been resolved:
kthread: unpark only parked kthread
Calling into kthread unparking unconditionally is mostly harmless when
the kthread is already unparked. The wake up is then simply ignored
because the target is not in TASK_PARKED state.
However if the kthread is per CPU, the wake up is preceded by a call
to kthread_bind() which expects the task to be inactive and in
TASK_PARKED state, which obviously isn't the case if it is unparked.
As a result, calling kthread_stop() on an unparked per-cpu kthread
triggers such a warning:
WARNING: CPU: 0 PID: 11 at kernel/kthread.c:525 __kthread_bind_mask kernel/kthread.c:525

Fix this with skipping unecessary unparking while stopping a kthread.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vdpa/mlx5: Fix invalid mr resource destroy
Certain error paths from mlx5_vdpa_dev_add() can end up releasing mr
resources which never got initialized in the first place.
This patch adds the missing check in mlx5_vdpa_destroy_mr_resources()
to block releasing non-initialized mr resources.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: Set correct chandef when starting CAC
When starting CAC in a mode other than AP mode, it return a
"WARNING: CPU: 0 PID: 63 at cfg80211_chandef_dfs_usable+0x20/0xaf [cfg80211]"
caused by the chandef.chan being null at the end of CAC.
Solution: Ensure the channel definition is set for the different modes
when starting CAC to avoid getting a NULL 'chan' at the end of CAC.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for head_pipe in dcn201_acquire_free_pipe_for_layer
This commit addresses a potential null pointer dereference issue in the
`dcn201_acquire_free_pipe_for_layer` function. The issue could occur
when `head_pipe` is null.
The fix adds a check to ensure `head_pipe` is not null before asserting
it. If `head_pipe` is null, the function returns NULL to prevent a
potential null pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/resource/dcn201/dcn201_resource.c:1016 dcn201_acquire_free_pipe_for_layer() error: we previously assumed 'head_pipe' could be null (see line 1010)

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for function pointer in dcn20_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the dcn20_set_output_transfer_func function. Previously,
set_output_gamma was being checked for null at line 1030, but then it
was being dereferenced without any null check at line 1048. This could
potentially lead to a null pointer dereference error if set_output_gamma
is null.
To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a null check for set_output_gamma
before the call to set_output_gamma at line 1048.

Summary
In the Linux kernel, the following vulnerability has been resolved:
jbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns error
In __jbd2_log_wait_for_space(), we might call jbd2_cleanup_journal_tail()
to recover some journal space. But if an error occurs while executing
jbd2_cleanup_journal_tail() (e.g., an EIO), we don't stop waiting for free
space right away, we try other branches, and if j_committing_transaction
is NULL (i.e., the tid is 0), we will get the following complain:
============================================
JBD2: I/O error when updating journal superblock for sdd-8.
__jbd2_log_wait_for_space: needed 256 blocks and only had 217 space available
__jbd2_log_wait_for_space: no way to get more journal space in sdd-8
------------[ cut here ]------------
WARNING: CPU: 2 PID: 139804 at fs/jbd2/checkpoint.c:109 __jbd2_log_wait_for_space+0x251/0x2e0
Modules linked in:

[...]
============================================
So only if jbd2_cleanup_journal_tail() returns 1, i.e., there is nothing to
clean up at the moment, continue to try to reclaim free space in other ways.
Note that this fix relies on commit 6f6a6fda2945 ("jbd2: fix ocfs2 corrupt
when updating journal superblock fails") to make jbd2_cleanup_journal_tail
return the correct error code.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: strict bound check before memcmp in ocfs2_xattr_find_entry()
xattr in ocfs2 maybe 'non-indexed', which saved with additional space
requested. It's better to check if the memory is out of bound before
memcmp, although this possibility mainly comes from crafted poisonous
images.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Pass non-null to dcn20_validate_apply_pipe_split_flags
[WHAT & HOW]
"dcn20_validate_apply_pipe_split_flags" dereferences merge, and thus it
cannot be a null pointer. Let's pass a valid pointer to avoid null
dereference.
This fixes 2 FORWARD_NULL issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mvneta: Prevent out of bounds read in mvneta_config_rss()
The pp->indir[0] value comes from the user. It is passed to:
if (cpu_online(pp->rxq_def))
inside the mvneta_percpu_elect() function. It needs bounds checkeding
to ensure that it is not beyond the end of the cpu bitmap.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error
Ensure index in rtl2830_pid_filter does not exceed 31 to prevent
out-of-bounds access.
dev->filters is a 32-bit value, so set_bit and clear_bit functions should
only operate on indices from 0 to 31. If index is 32, it will attempt to
access a non-existent 33rd bit, leading to out-of-bounds access.
Change the boundary check from index > 32 to index >= 32 to resolve this
issue.

Summary
In the Linux kernel, the following vulnerability has been resolved:
idpf: fix memory leaks and crashes while performing a soft reset
The second tagged commit introduced a UAF, as it removed restoring
q_vector->vport pointers after reinitializating the structures.
This is due to that all queue allocation functions are performed here
with the new temporary vport structure and those functions rewrite
the backpointers to the vport. Then, this new struct is freed and
the pointers start leading to nowhere.
But generally speaking, the current logic is very fragile. It claims
to be more reliable when the system is low on memory, but in fact, it
consumes two times more memory as at the moment of running this
function, there are two vports allocated with their queues and vectors.
Moreover, it claims to prevent the driver from running into "bad state",
but in fact, any error during the rebuild leaves the old vport in the
partially allocated state.
Finally, if the interface is down when the function is called, it always
allocates a new queue set, but when the user decides to enable the
interface later on, vport_open() allocates them once again, IOW there's
a clear memory leak here.
Just don't allocate a new queue set when performing a reset, that solves
crashes and memory leaks. Readd the old queue number and reopen the
interface on rollback - that solves limbo states when the device is left
disabled and/or without HW queues enabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix increasing MSI-X on VF
Increasing MSI-X value on a VF leads to invalid memory operations. This
is caused by not reallocating some arrays.
Reproducer:
modprobe ice
echo 0 > /sys/bus/pci/devices/$PF_PCI/sriov_drivers_autoprobe
echo 1 > /sys/bus/pci/devices/$PF_PCI/sriov_numvfs
echo 17 > /sys/bus/pci/devices/$VF0_PCI/sriov_vf_msix_count
Default MSI-X is 16, so 17 and above triggers this issue.
KASAN reports:
BUG: KASAN: slab-out-of-bounds in ice_vsi_alloc_ring_stats+0x38d/0x4b0 [ice]

sriov_numvfs_store+0x212/0x390
(...)
To fix it, use ice_vsi_rebuild() instead of ice_vf_reconfig_vsi(). This
causes the required arrays to be reallocated taking the new queue count
into account (ice_vsi_realloc_stat_arrays()). Set req_txq and req_rxq
before ice_vsi_rebuild(), so that realloc uses the newly set queue
count.
Additionally, ice_vsi_rebuild() does not remove VSI filters
(ice_fltr_remove_all()), so ice_vf_init_host_cfg() is no longer
necessary.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Remove tst_run from lwt_seg6local_prog_ops.
The syzbot reported that the lwt_seg6 related BPF ops can be invoked
via bpf_test_run() without without entering input_action_end_bpf()
first.
Martin KaFai Lau said that self test for BPF_PROG_TYPE_LWT_SEG6LOCAL
probably didn't work since it was introduced in commit 04d4b274e2a
("ipv6: sr: Add seg6local action End.BPF"). The reason is that the
per-CPU variable seg6_bpf_srh_states::srh is never assigned in the self
test case but each BPF function expects it.
Remove test_run for BPF_PROG_TYPE_LWT_SEG6LOCAL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing: Free buffers when a used dynamic event is removed
After 65536 dynamic events have been added and removed, the "type" field
of the event then uses the first type number that is available (not
currently used by other events). A type number is the identifier of the
binary blobs in the tracing ring buffer (known as events) to map them to
logic that can parse the binary blob.
The issue is that if a dynamic event (like a kprobe event) is traced and
is in the ring buffer, and then that event is removed (because it is
dynamic, which means it can be created and destroyed), if another dynamic
event is created that has the same number that new event's logic on
parsing the binary blob will be used.
To show how this can be an issue, the following can crash the kernel:
# cd /sys/kernel/tracing
# for i in `seq 65536`; do
echo 'p:kprobes/foo do_sys_openat2 $arg1:u32' > kprobe_events
# done
For every iteration of the above, the writing to the kprobe_events will
remove the old event and create a new one (with the same format) and
increase the type number to the next available on until the type number
reaches over 65535 which is the max number for the 16 bit type. After it
reaches that number, the logic to allocate a new number simply looks for
the next available number. When an dynamic event is removed, that number
is then available to be reused by the next dynamic event created. That is,
once the above reaches the max number, the number assigned to the event in
that loop will remain the same.
Now that means deleting one dynamic event and created another will reuse
the previous events type number. This is where bad things can happen.
After the above loop finishes, the kprobes/foo event which reads the
do_sys_openat2 function call's first parameter as an integer.
# echo 1 > kprobes/foo/enable
# cat /etc/passwd > /dev/null
# cat trace
cat-2211 [005] .... 2007.849603: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196
cat-2211 [005] .... 2007.849620: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196
cat-2211 [005] .... 2007.849838: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196
cat-2211 [005] .... 2007.849880: foo: (do_sys_openat2+0x0/0x130) arg1=4294967196
# echo 0 > kprobes/foo/enable
Now if we delete the kprobe and create a new one that reads a string:
# echo 'p:kprobes/foo do_sys_openat2 +0($arg2):string' > kprobe_events
And now we can the trace:
# cat trace
sendmail-1942 [002] ..... 530.136320: foo: (do_sys_openat2+0x0/0x240) arg1= cat-2046 [004] ..... 530.930817: foo: (do_sys_openat2+0x0/0x240) arg1="������������������������������������������������������������������������������������������������"

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: Fix an unsafe loop on the list
The kernel may crash when deleting a genetlink family if there are still
listeners for that family:
Oops: Kernel access of bad area, sig: 11 [#1]
...
NIP [c000000000c080bc] netlink_update_socket_mc+0x3c/0xc0
LR [c000000000c0f764] __netlink_clear_multicast_users+0x74/0xc0
Call Trace:
__netlink_clear_multicast_users+0x74/0xc0
genl_unregister_family+0xd4/0x2d0
Change the unsafe loop on the list to a safe one, because inside the
loop there is an element removal from this list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
efi: fix NULL-deref in init error path
In cases where runtime services are not supported or have been disabled,
the runtime services workqueue will never have been allocated.
Do not try to destroy the workqueue unconditionally in the unlikely
event that EFI initialisation fails to avoid dereferencing a NULL
pointer.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix NULL pointer access in mt7921_ipv6_addr_change
When disabling wifi mt7921_ipv6_addr_change() is called as a notifier.
At this point mvif->phy is already NULL so we cannot use it here.

Summary
In the Linux kernel, the following vulnerability has been resolved:
serial: protect uart_port_dtr_rts() in uart_shutdown() too
Commit af224ca2df29 (serial: core: Prevent unsafe uart port access, part
3) added few uport == NULL checks. It added one to uart_shutdown(), so
the commit assumes, uport can be NULL in there. But right after that
protection, there is an unprotected "uart_port_dtr_rts(uport, false);"
call. That is invoked only if HUPCL is set, so I assume that is the
reason why we do not see lots of these reports.
Or it cannot be NULL at this point at all for some reason :P.
Until the above is investigated, stay on the safe side and move this
dereference to the if too.
I got this inconsistency from Coverity under CID 1585130. Thanks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
slip: make slhc_remember() more robust against malicious packets
syzbot found that slhc_remember() was missing checks against
malicious packets [1].
slhc_remember() only checked the size of the packet was at least 20,
which is not good enough.
We need to make sure the packet includes the IPv4 and TCP header
that are supposed to be carried.
Add iph and th pointers to make the code more readable.

Summary
In the Linux kernel, the following vulnerability has been resolved:
NFC: nci: Bounds check struct nfc_target arrays
While running under CONFIG_FORTIFY_SOURCE=y, syzkaller reported:
memcpy: detected field-spanning write (size 129) of single field "target->sensf_res" at net/nfc/nci/ntf.c:260 (size 18)
This appears to be a legitimate lack of bounds checking in
nci_add_new_protocol(). Add the missing checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation
This commit addresses a potential index out of bounds issue in the
`cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30
color management module. The issue could occur when the index 'i'
exceeds the number of transfer function points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, the function returns
false to indicate an error.
Reported by smatch:

Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: lpi2c: Avoid calling clk_get_rate during transfer
Instead of repeatedly calling clk_get_rate for each transfer, lock
the clock rate and cache the value.
A deadlock has been observed while adding tlv320aic32x4 audio codec to
the system. When this clock provider adds its clock, the clk mutex is
locked already, it needs to access i2c, which in return needs the mutex
for clk_get_rate as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: uvc: Prevent buffer overflow in setup handler
Setup function uvc_function_setup permits control transfer
requests with up to 64 bytes of payload (UVC_MAX_REQUEST_SIZE),
data stage handler for OUT transfer uses memcpy to copy req->actual
bytes to uvc_event->data.data array of size 60. This may result
in an overflow of 4 bytes.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: use two-phase skb reclamation in ieee80211_do_stop()
Since '__dev_queue_xmit()' should be called with interrupts enabled,
the following backtrace:
ieee80211_do_stop()
...
spin_lock_irqsave(&local->queue_stop_reason_lock, flags)
...
ieee80211_free_txskb()
ieee80211_report_used_skb()
ieee80211_report_ack_skb()
cfg80211_mgmt_tx_status_ext()
nl80211_frame_tx_status()
genlmsg_multicast_netns()
genlmsg_multicast_netns_filtered()

netlink_broadcast_deliver()
__netlink_sendskb()
netlink_deliver_tap()
__netlink_deliver_tap_skb()
dev_queue_xmit()
__dev_queue_xmit() ; with IRQS disabled
...
spin_unlock_irqrestore(&local->queue_stop_reason_lock, flags)
issues the warning (as reported by syzbot reproducer):
WARNING: CPU: 2 PID: 5128 at kernel/softirq.c:362 __local_bh_enable_ip+0xc3/0x120
Fix this by implementing a two-phase skb reclamation in
'ieee80211_do_stop()', where actual work is performed
outside of a section with interrupts disabled.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/adreno: Assign msm_gpu->pdev earlier to avoid nullptrs
There are some cases, such as the one uncovered by Commit 46d4efcccc68
("drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails")
where
msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL);
is called on gpu->pdev == NULL, as the GPU device has not been fully
initialized yet.
Turns out that there's more than just the aforementioned path that
causes this to happen (e.g. the case when there's speedbin data in the
catalog, but opp-supported-hw is missing in DT).
Assigning msm_gpu->pdev earlier seems like the least painful solution
to this, therefore do so.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: Acquire kvm->srcu when handling KVM_SET_VCPU_EVENTS
Grab kvm->srcu when processing KVM_SET_VCPU_EVENTS, as KVM will forcibly
leave nested VMX/SVM if SMM mode is being toggled, and leaving nested VMX
reads guest memory.
Note, kvm_vcpu_ioctl_x86_set_vcpu_events() can also be called from KVM_RUN
via sync_regs(), which already holds SRCU. I.e. trying to precisely use
kvm_vcpu_srcu_read_lock() around the problematic SMM code would cause
problems. Acquiring SRCU isn't all that expensive, so for simplicity,
grab it unconditionally for KVM_SET_VCPU_EVENTS.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix i_data_sem unlock order in ext4_ind_migrate()
Fuzzing reports a possible deadlock in jbd2_log_wait_commit.
This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require
synchronous updates because the file descriptor is opened with O_SYNC.
This can lead to the jbd2_journal_stop() function calling
jbd2_might_wait_for_commit(), potentially causing a deadlock if the
EXT4_IOC_MIGRATE call races with a write(2) system call.
This problem only arises when CONFIG_PROVE_LOCKING is enabled. In this
case, the jbd2_might_wait_for_commit macro locks jbd2_handle in the
jbd2_journal_stop function while i_data_sem is locked. This triggers
lockdep because the jbd2_journal_start function might also lock the same
jbd2_handle simultaneously.
Found by Linux Verification Center (linuxtesting.org) with syzkaller.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointers before multiple uses
[WHAT & HOW]
Poniters, such as stream_enc and dc->bw_vbios, are null checked previously
in the same function, so Coverity warns "implies that stream_enc and
dc->bw_vbios might be null". They are used multiple times in the
subsequent code and need to be checked.
This fixes 10 FORWARD_NULL issues reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Check debug trap enable before write dbg_ev_file
In interrupt context, write dbg_ev_file will be run by work queue. It
will cause write dbg_ev_file execution after debug_trap_disable, which
will cause NULL pointer access.
v2: cancel work "debug_event_workarea" before set dbg_ev_file as NULL.

Summary
In the Linux kernel, the following vulnerability has been resolved:
crypto: hisilicon/qm - inject error before stopping queue
The master ooo cannot be completely closed when the
accelerator core reports memory error. Therefore, the driver
needs to inject the qm error to close the master ooo. Currently,
the qm error is injected after stopping queue, memory may be
released immediately after stopping queue, causing the device to
access the released memory. Therefore, error is injected to close master
ooo before stopping queue to ensure that the device does not access
the released memory.

Summary
In the Linux kernel, the following vulnerability has been resolved:
fsnotify: clear PARENT_WATCHED flags lazily
In some setups directories can have many (usually negative) dentries.
Hence __fsnotify_update_child_dentry_flags() function can take a
significant amount of time. Since the bulk of this function happens
under inode->i_lock this causes a significant contention on the lock
when we remove the watch from the directory as the
__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()
races with __fsnotify_update_child_dentry_flags() calls from
__fsnotify_parent() happening on children. This can lead upto softlockup
reports reported by users.
Fix the problem by calling fsnotify_update_children_dentry_flags() to
set PARENT_WATCHED flags only when parent starts watching children.
When parent stops watching children, clear false positive PARENT_WATCHED
flags lazily in __fsnotify_parent() for each accessed child.

[Analysis]
gsm_msg on the tx_ctrl_list or tx_data_list of gsm_mux
can be freed by multi threads through ioctl,which leads
to the occurrence of uaf. Protect it by gsm tx lock.

Summary
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: altera-msgdma: properly free descriptor in msgdma_free_descriptor
Remove list_del call in msgdma_chan_desc_cleanup, this should be the role
of msgdma_free_descriptor. In consequence replace list_add_tail with
list_move_tail in msgdma_free_descriptor.
This fixes the path:
msgdma_free_chan_resources -> msgdma_free_descriptors ->
msgdma_free_desc_list -> msgdma_free_descriptor
which does not correctly free the descriptors as first nodes were not
removed from the list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: rockchip: Resolve unbalanced runtime PM / system PM handling
Commit e882575efc77 ("spi: rockchip: Suspend and resume the bus during
NOIRQ_SYSTEM_SLEEP_PM ops") stopped respecting runtime PM status and
simply disabled clocks unconditionally when suspending the system. This
causes problems when the device is already runtime suspended when we go
to sleep -- in which case we double-disable clocks and produce a
WARNing.
Switch back to pm_runtime_force_{suspend,resume}(), because that still
seems like the right thing to do, and the aforementioned commit makes no
explanation why it stopped using it.
Also, refactor some of the resume() error handling, because it's not
actually a good idea to re-disable clocks on failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xen-netfront: Fix NULL sring after live migration
A NAPI is setup for each network sring to poll data to kernel
The sring with source host is destroyed before live migration and
new sring with target host is setup after live migration.
The NAPI for the old sring is not deleted until setup new sring
with target host after migration. With busy_poll/busy_read enabled,
the NAPI can be polled before got deleted when resume VM.

xen frontend should remove the NAPIs for the old srings before live
migration as the bond srings are destroyed
There is a tiny window between the srings are set to NULL and
the NAPIs are disabled, It is safe as the NAPI threads are still
frozen at that time

Summary
In the Linux kernel, the following vulnerability has been resolved:
usbnet: ipheth: do not stop RX on failing RX callback
RX callbacks can fail for multiple reasons:
* Payload too short
* Payload formatted incorrecly (e.g. bad NCM framing)
* Lack of memory
None of these should cause the driver to seize up.
Make such failures non-critical and continue processing further
incoming URBs.

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/rtrs-srv: Avoid null pointer deref during path establishment
For RTRS path establishment, RTRS client initiates and completes con_num
of connections. After establishing all its connections, the information
is exchanged between the client and server through the info_req message.
During this exchange, it is essential that all connections have been
established, and the state of the RTRS srv path is CONNECTED.
So add these sanity checks, to make sure we detect and abort process in
error scenarios to avoid null pointer deref.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error
For all non-tracing helpers which formerly had ARG_PTR_TO_{LONG,INT} as input
arguments, zero the value for the case of an error as otherwise it could leak
memory. For tracing, it is not needed given CAP_PERFMON can already read all
kernel memory anyway hence bpf_get_func_arg() and bpf_get_func_ret() is skipped
in here.
Also, the MTU helpers mtu_len pointer value is being written but also read.
Technically, the MEM_UNINIT should not be there in order to always force init.
Removing MEM_UNINIT needs more verifier rework though: MEM_UNINIT right now
implies two things actually: i) write into memory, ii) memory does not have
to be initialized. If we lift MEM_UNINIT, it then becomes: i) read into memory,
ii) memory must be initialized. This means that for bpf_*_check_mtu() we're
readding the issue we're trying to fix, that is, it would then be able to
write back into things like .rodata BPF maps. Follow-up work will rework the
MEM_UNINIT semantics such that the intent can be better expressed. For now
just clear the *mtu_len on error path which can be lifted later again.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: fix null-ptr-deref while probe() failed
I got a null-ptr-deref report as following when doing fault injection test:
BUG: kernel NULL pointer dereference, address: 0000000000000058

klist_remove() <- knode_driver is not added yet, cause null-ptr-deref
In phy_attach_direct(), after setting the 'dev->driver', probe() fails,
device_bind_driver() is not called, so the knode_driver->n_klist is not
set, then it causes null-ptr-deref in __device_release_driver() while
deleting device. Fix this by setting dev->driver to NULL in the error
path in phy_attach_direct().

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for top_pipe_to_program in commit_planes_for_stream
This commit addresses a null pointer dereference issue in the
`commit_planes_for_stream` function at line 4140. The issue could occur
when `top_pipe_to_program` is null.
The fix adds a check to ensure `top_pipe_to_program` is not null before
accessing its stream_res. This prevents a null pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 commit_planes_for_stream() error: we previously assumed 'top_pipe_to_program' could be null (see line 3906)

Summary
In the Linux kernel, the following vulnerability has been resolved:
i3c: master: svc: Fix use after free vulnerability in svc_i3c_master Driver Due to Race Condition
In the svc_i3c_master_probe function, &master->hj_work is bound with
svc_i3c_master_hj_work, &master->ibi_work is bound with
svc_i3c_master_ibi_work. And svc_i3c_master_ibi_work can start the
hj_work, svc_i3c_master_irq_handler can start the ibi_work.
If we remove the module which will call svc_i3c_master_remove to
make cleanup, it will free master->base through i3c_master_unregister
while the work mentioned above will be used. The sequence of operations
that may lead to a UAF bug is as follows:
CPU0 CPU1
| svc_i3c_master_hj_work
svc_i3c_master_remove |
i3c_master_unregister(&master->base)|
device_unregister(&master->dev) |
device_release |
//free master->base |
| i3c_master_do_daa(&master->base)
| //use master->base
Fix it by ensuring that the work is canceled before proceeding with the
cleanup in svc_i3c_master_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpiolib: fix memory leak in gpiochip_setup_dev()
Here is a backtrace report about memory leak detected in
gpiochip_setup_dev():
unreferenced object 0xffff88810b406400 (size 512):
comm "python3", pid 1682, jiffies 4295346908 (age 24.090s)
backtrace:
kmalloc_trace
device_add device_private_init at drivers/base/core.c:3361
(inlined by) device_add at drivers/base/core.c:3411
cdev_device_add
gpiolib_cdev_register
gpiochip_setup_dev
gpiochip_add_data_with_key
gcdev_register() & gcdev_unregister() would call device_add() &
device_del() (no matter CONFIG_GPIO_CDEV is enabled or not) to
register/unregister device.
However, if device_add() succeeds, some resource (like
struct device_private allocated by device_private_init())
is not released by device_del().
Therefore, after device_add() succeeds by gcdev_register(), it
needs to call put_device() to release resource in the error handle
path.
Here we move forward the register of release function, and let it
release every piece of resource by put_device() instead of kfree().
While at it, fix another subtle issue, i.e. when gc->ngpio is equal
to 0, we still call kcalloc() and, in case of further error, kfree()
on the ZERO_PTR pointer, which is not NULL. It's not a bug per se,
but rather waste of the resources and potentially wrong expectation
about contents of the gdev->descs variable.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: dsa: sja1105: avoid out of bounds access in sja1105_init_l2_policing()
The SJA1105 family has 45 L2 policing table entries
(SJA1105_MAX_L2_POLICING_COUNT) and SJA1110 has 110
(SJA1110_MAX_L2_POLICING_COUNT). Keeping the table structure but
accounting for the difference in port count (5 in SJA1105 vs 10 in
SJA1110) does not fully explain the difference. Rather, the SJA1110 also
has L2 ingress policers for multicast traffic. If a packet is classified
as multicast, it will be processed by the policer index 99 + SRCPORT.
The sja1105_init_l2_policing() function initializes all L2 policers such
that they don't interfere with normal packet reception by default. To have
a common code between SJA1105 and SJA1110, the index of the multicast
policer for the port is calculated because it's an index that is out of
bounds for SJA1105 but in bounds for SJA1110, and a bounds check is
performed.
The code fails to do the proper thing when determining what to do with the
multicast policer of port 0 on SJA1105 (ds->num_ports = 5). The "mcast"
index will be equal to 45, which is also equal to
table->ops->max_entry_count (SJA1105_MAX_L2_POLICING_COUNT). So it passes
through the check. But at the same time, SJA1105 doesn't have multicast
policers. So the code programs the SHARINDX field of an out-of-bounds
element in the L2 Policing table of the static config.
The comparison between index 45 and 45 entries should have determined the
code to not access this policer index on SJA1105, since its memory wasn't
even allocated.
With enough bad luck, the out-of-bounds write could even overwrite other
valid kernel data, but in this case, the issue was detected using KASAN.

[Analysis]
There are two paths (dbUnmount and jfs_ioc_trim) that generate race
condition when accessing bmap, which leads to the occurrence of uaf.
Use the lock s_umount to synchronize them, in order to avoid uaf caused
by race condition.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tracing/timerlat: Fix a race during cpuhp processing
There is another found exception that the "timerlat/1" thread was
scheduled on CPU0, and lead to timer corruption finally:
```
ODEBUG: init active (active state 0) object: ffff888237c2e108 object type: hrtimer hint: timerlat_irq+0x0/0x220

</TASK>
```
After tracing the scheduling event, it was discovered that the migration
of the "timerlat/1" thread was performed during thread creation. Further
analysis confirmed that it is because the CPU online processing for
osnoise is implemented through workers, which is asynchronous with the
offline processing. When the worker was scheduled to create a thread, the
CPU may has already been removed from the cpu_online_mask during the offline
process, resulting in the inability to select the right CPU:
T1 | T2
[CPUHP_ONLINE] | cpu_device_down()
osnoise_hotplug_workfn() |
| cpus_write_lock()
| takedown_cpu(1)
| cpus_write_unlock()
[CPUHP_OFFLINE] |
cpus_read_lock() |
start_kthread(1) |
cpus_read_unlock() |
To fix this, skip online processing if the CPU is already offline.

wifi: ath11k: fix htt pktlog locking
The ath11k active pdevs are protected by RCU but the htt pktlog handling
code calling ath11k_mac_get_ar_by_pdev_id() was not marked as a
read-side critical section.
Mark the code in question as an RCU read-side critical section to avoid
any potential use-after-free issues.
Compile tested only.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: Fix improper handling of refcount in ice_sriov_set_msix_vec_count()
This patch addresses an issue with improper reference count handling in the
ice_sriov_set_msix_vec_count() function.
First, the function calls ice_get_vf_by_id(), which increments the
reference count of the vf pointer. If the subsequent call to
ice_get_vf_vsi() fails, the function currently returns an error without
decrementing the reference count of the vf pointer, leading to a reference
count leak. The correct behavior, as implemented in this patch, is to
decrement the reference count using ice_put_vf(vf) before returning an
error when vsi is NULL.
Second, the function calls ice_sriov_get_irqs(), which sets
vf->first_vector_idx. If this call returns a negative value, indicating an
error, the function returns an error without decrementing the reference
count of the vf pointer, resulting in another reference count leak. The
patch addresses this by adding a call to ice_put_vf(vf) before returning
an error when vf->first_vector_idx < 0.
This bug was identified by an experimental static analysis tool developed
by our team. The tool specializes in analyzing reference count operations
and identifying potential mismanagement of reference counts. In this case,
the tool flagged the missing decrement operation as a potential issue,
leading to this patch.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: avoid leaving partial pfn mappings around in error case
As Jann points out, PFN mappings are special, because unlike normal
memory mappings, there is no lifetime information associated with the
mapping - it is just a raw mapping of PFNs with no reference counting of
a 'struct page'.
That's all very much intentional, but it does mean that it's easy to
mess up the cleanup in case of errors. Yes, a failed mmap() will always
eventually clean up any partial mappings, but without any explicit
lifetime in the page table mapping itself, it's very easy to do the
error handling in the wrong order.
In particular, it's easy to mistakenly free the physical backing store
before the page tables are actually cleaned up and (temporarily) have
stale dangling PTE entries.
To make this situation less error-prone, just make sure that any partial
pfn mapping is torn down early, before any other error handling.

Summary
In the Linux kernel, the following vulnerability has been resolved:
vhost/scsi: null-ptr-dereference in vhost_scsi_get_req()
Since commit 3f8ca2e115e5 ("vhost/scsi: Extract common handling code
from control queue handler") a null pointer dereference bug can be
triggered when guest sends an SCSI AN request.
In vhost_scsi_ctl_handle_vq(), `vc.target` is assigned with
`&v_req.tmf.lun[1]` within a switch-case block and is then passed to
vhost_scsi_get_req() which extracts `vc->req` and `tpg`. However, for
a `VIRTIO_SCSI_T_AN_*` request, tpg is not required, so `vc.target` is
set to NULL in this branch. Later, in vhost_scsi_get_req(),
`vc->target` is dereferenced without being checked, leading to a null
pointer dereference bug. This bug can be triggered from guest.
When this bug occurs, the vhost_worker process is killed while holding
`vq->mutex` and the corresponding tpg will remain occupied
indefinitely.
Below is the KASAN report:

This bug can be triggered from guest.\n\nWhen this bug occurs, the vhost_worker process is killed while holding\n`vq-\u003emutex` and the corresponding tpg will remain occupied\nindefinitely.\n\nBelow is the KASAN report:\nOops: general protection fault, probably for non-canonical address\n0xdffffc0000000000: 0000 [#1] PREEMPT SMP KASAN NOPTI\nKASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007]\nCPU: 1 PID: 840 Comm: poc Not tainted 6.10.0+ #1\nHardware name: QEMU Ubuntu 24.04 PC (i440FX + PIIX, 1996), BIOS\n1.16.3-debian-1.16.3-2 04/01/2014\nRIP: 0010:vhost_scsi_get_req+0x165/0x3a0\nCode: 00 fc ff df 48 89 fa 48 c1 ea 03 80 3c 02 00 0f 85 2b 02 00 00\n48 b8 00 00 00 00 00 fc ff df 4d 8b 65 30 4c 89 e2 48 c1 ea 03 \u003c0f\u003e b6\n04 02 4c 89 e2 83 e2 07 38 d0 7f 08 84 c0 0f 85 be 01 00 00\nRSP: 0018:ffff888017affb50 EFLAGS: 00010246\nRAX: dffffc0000000000 RBX: ffff88801b000000 RCX: 0000000000000000\nRDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff888017affcb8\nRBP: ffff888017affb80 R08: 0000000000000000 R09: 0000000000000000\nR10: 0000000000000000 R11: 0000000000000000 R12: 0000000000000000\nR13: ffff888017affc88 R14: ffff888017affd1c R15: ffff888017993000\nFS: 000055556e076500(0000) GS:ffff88806b100000(0000) knlGS:0000000000000000\nCS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\nCR2: 00000000200027c0 CR3: 0000000010ed0004 CR4: 0000000000370ef0\nCall Trace:\n \u003cTASK\u003e\n ? show_regs+0x86/0xa0\n ? die_addr+0x4b/0xd0\n ? exc_general_protection+0x163/0x260\n ? asm_exc_general_protection+0x27/0x30\n ? vhost_scsi_get_req+0x165/0x3a0\n vhost_scsi_ctl_handle_vq+0x2a4/0xca0\n ? __pfx_vhost_scsi_ctl_handle_vq+0x10/0x10\n ? __switch_to+0x721/0xeb0\n ? __schedule+0xda5/0x5710\n ? __kasan_check_write+0x14/0x30\n ? _raw_spin_lock+0x82/0xf0\n vhost_scsi_ctl_handle_kick+0x52/0x90\n vhost_run_work_list+0x134/0x1b0\n vhost_task_fn+0x121/0x350\n...\n \u003c/TASK\u003e\n---[ end trace 0000000000000000 ]---\n\nLet\u0027s add a check in vhost_scsi_get_req.\n\n[whitespace fixes]"

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: update orig_path in ext4_find_extent()
In ext4_find_extent(), if the path is not big enough, we free it and set
*orig_path to NULL. But after reallocating and successfully initializing
the path, we don't update *orig_path, in which case the caller gets a
valid path but a NULL ppath, and this may cause a NULL pointer dereference
or a path memory leak. For example:
ext4_split_extent
path = *ppath = 2000
ext4_find_extent
if (depth > path[0].p_maxdepth)
kfree(path = 2000);
*orig_path = path = NULL;
path = kcalloc() = 3000
ext4_split_extent_at(*ppath = NULL)
path = *ppath;
ex = path[depth].p_ext;
// NULL pointer dereference!
==================================================================
BUG: kernel NULL pointer dereference, address: 0000000000000010
CPU: 6 UID: 0 PID: 576 Comm: fsstress Not tainted 6.11.0-rc2-dirty #847
RIP: 0010:ext4_split_extent_at+0x6d/0x560
Call Trace:
<TASK>

ext4_map_blocks+0x2b0/0x690
ext4_iomap_begin+0x20e/0x2c0
[...]
==================================================================
Therefore, *orig_path is updated when the extent lookup succeeds, so that
the caller can safely use path or *ppath.

Summary
In the Linux kernel, the following vulnerability has been resolved:
char: tpm: Protect tpm_pm_suspend with locks
Currently tpm transactions are executed unconditionally in
tpm_pm_suspend() function, which may lead to races with other tpm
accessors in the system.
Specifically, the hw_random tpm driver makes use of tpm_get_random(),
and this function is called in a loop from a kthread, which means it's
not frozen alongside userspace, and so can race with the work done
during system suspend:
tpm tpm0: tpm_transmit: tpm_recv: error -52
tpm tpm0: invalid TPM_STS.x 0xff, dumping stack for forensics
CPU: 0 PID: 1 Comm: init Not tainted 6.1.0-rc5+ #135
Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 1.16.0-20220807_005459-localhost 04/01/2014
Call Trace:
tpm_tis_status.cold+0x19/0x20
tpm_transmit+0x13b/0x390
tpm_transmit_cmd+0x20/0x80
tpm1_pm_suspend+0xa6/0x110
tpm_pm_suspend+0x53/0x80
__pnp_bus_suspend+0x35/0xe0
__device_suspend+0x10f/0x350
Fix this by calling tpm_try_get_ops(), which itself is a wrapper around
tpm_chip_start(), but takes the appropriate mutex.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/tdx: Fix "in-kernel MMIO" check
TDX only supports kernel-initiated MMIO operations. The handle_mmio()
function checks if the #VE exception occurred in the kernel and rejects
the operation if it did not.
However, userspace can deceive the kernel into performing MMIO on its
behalf. For example, if userspace can point a syscall to an MMIO address,
syscall does get_user() or put_user() on it, triggering MMIO #VE. The
kernel will treat the #VE as in-kernel MMIO.
Ensure that the target MMIO address is within the kernel before decoding
instruction.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ipv6: avoid use-after-free in ip6_fragment()
Blamed commit claimed rcu_read_lock() was held by ip6_fragment() callers.
It seems to not be always true, at least for UDP stack.
syzbot reported:

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/mm/ident_map: Use gbpages only where full GB page should be mapped.
When ident_pud_init() uses only GB pages to create identity maps, large
ranges of addresses not actually requested can be included in the resulting
table; a 4K request will map a full GB. This can include a lot of extra
address space past that requested, including areas marked reserved by the
BIOS. That allows processor speculation into reserved regions, that on UV
systems can cause system halts.
Only use GB pages when map creation requests include the full GB page of
space. Fall back to using smaller 2M pages when only portions of a GB page
are included in the request.
No attempt is made to coalesce mapping requests. If a request requires a
map entry at the 2M (pmd) level, subsequent mapping requests within the
same 1G region will also be at the pmd level, even if adjacent or
overlapping such requests could have been combined to map a full GB page.
Existing usage starts with larger regions and then adds smaller regions, so
this should not have any great consequence.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit
Syzbot points out that skb_trim() has a sanity check on the existing length of
the skb, which can be uninitialised in some error paths. The intent here is
clearly just to reset the length to zero before resubmitting, so switch to
calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()
already contains a call to skb_reset_tail_pointer(), so remove the redundant
call.
The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar
usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Fix PCI device refcount leak in dmar_dev_scope_init()
for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.
If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() for the error path to avoid reference count leak.

This is because TFM is being used in parallel.
Fix this by allocating a new AEAD TFM for async decryption, but keep
the existing one for synchronous READ cases (similar to what is done

Also remove the calls to aead_request_set_callback() and
crypto_wait_req() since it's always going to be a synchronous operation.

Summary
In the Linux kernel, the following vulnerability has been resolved:
spi: hisi-kunpeng: Add verification for the max_frequency provided by the firmware
If the value of max_speed_hz is 0, it may cause a division by zero
error in hisi_calc_effective_speed().
The value of max_speed_hz is provided by firmware.
Firmware is generally considered as a trusted domain. However, as
division by zero errors can cause system failure, for defense measure,
the value of max_speed is validated here. So 0 is regarded as invalid
and an error code is returned.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: avoid potential underflow in qdisc_pkt_len_init() with UFO
After commit 7c6d2ecbda83 ("net: be more gentle about silly gso
requests coming from user") virtio_net_hdr_to_skb() had sanity check
to detect malicious attempts from user space to cook a bad GSO packet.
Then commit cf9acc90c80ec ("net: virtio_net_hdr_to_skb: count
transport header in UFO") while fixing one issue, allowed user space
to cook a GSO packet with the following characteristic :
IPv4 SKB_GSO_UDP, gso_size=3, skb->len = 28.
When this packet arrives in qdisc_pkt_len_init(), we end up
with hdr_len = 28 (IPv4 header + UDP header), matching skb->len
Then the following sets gso_segs to 0 :
gso_segs = DIV_ROUND_UP(skb->len - hdr_len,
shinfo->gso_size);
Then later we set qdisc_skb_cb(skb)->pkt_len to back to zero :/
qdisc_skb_cb(skb)->pkt_len += (gso_segs - 1) * hdr_len;
This leads to the following crash in fq_codel [1]
qdisc_pkt_len_init() is best effort, we only want an estimation
of the bytes sent on the wire, not crashing the kernel.
This patch is fixing this particular issue, a following one
adds more sanity checks for another potential bug.

Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps:
Don't track CMA dma-buf pages under RssFile") it was possible to obtain
a mapping larger than the buffer size via mremap and bypass the overflow
check in dma_buf_mmap_internal. When using such a mapping to attempt to
fault past the end of the buffer, the CMA heap fault handler also checks
the fault offset against the buffer size, but gets the boundary wrong by
1. Fix the boundary check so that we don't read off the end of the pages
array and insert an arbitrary page in the mapping.

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: Use dedicated mutex to protect kvm_usage_count to avoid deadlock
Use a dedicated mutex to guard kvm_usage_count to fix a potential deadlock
on x86 due to a chain of locks and SRCU synchronizations. Translating the
below lockdep splat, CPU1 #6 will wait on CPU0 #1, CPU0 #8 will wait on
CPU2 #3, and CPU2 #7 will wait on CPU1 #4 (if there's a writer, due to the
fairness of r/w semaphores).
CPU0 CPU1 CPU2
1 lock(&kvm->slots_lock);
2 lock(&vcpu->mutex);
3 lock(&kvm->srcu);
4 lock(cpu_hotplug_lock);
5 lock(kvm_lock);
6 lock(&kvm->slots_lock);
7 lock(cpu_hotplug_lock);
8 sync(&kvm->srcu);
Note, there are likely more potential deadlocks in KVM x86, e.g. the same
pattern of taking cpu_hotplug_lock outside of kvm_lock likely exists with
__kvmclock_cpufreq_notifier():
cpuhp_cpufreq_online()
|
-> cpufreq_online()
|
-> cpufreq_gov_performance_limits()
|
-> __cpufreq_driver_target()
|
-> __target_index()
|
-> cpufreq_freq_transition_begin()
|
-> cpufreq_notify_transition()
|
-> ... __kvmclock_cpufreq_notifier()
But, actually triggering such deadlocks is beyond rare due to the
combination of dependencies and timings involved. E.g. the cpufreq
notifier is only used on older CPUs without a constant TSC, mucking with
the NX hugepage mitigation while VMs are running is very uncommon, and
doing so while also onlining/offlining a CPU (necessary to generate
contention on cpu_hotplug_lock) would be even more unusual.
The most robust solution to the general cpu_hotplug_lock issue is likely
to switch vm_list to be an RCU-protected list, e.g. so that x86's cpufreq
notifier doesn't to take kvm_lock. For now, settle for fixing the most
blatant deadlock, as switching to an RCU-protected list is a much more
involved change, but add a comment in locking.rst to call out that care
needs to be taken when walking holding kvm_lock and walking vm_list.

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: Use dedicated mutex to protect kvm_usage_count to avoid deadlock\n\nUse a dedicated mutex to guard kvm_usage_count to fix a potential deadlock\non x86 due to a chain of locks and SRCU synchronizations. Translating the\nbelow lockdep splat, CPU1 #6 will wait on CPU0 #1, CPU0 #8 will wait on\nCPU2 #3, and CPU2 #7 will wait on CPU1 #4 (if there\u0027s a writer, due to the\nfairness of r/w semaphores).\n\n CPU0 CPU1 CPU2\n1 lock(\u0026kvm-\u003eslots_lock);\n2 lock(\u0026vcpu-\u003emutex);\n3 lock(\u0026kvm-\u003esrcu);\n4 lock(cpu_hotplug_lock);\n5 lock(kvm_lock);\n6 lock(\u0026kvm-\u003eslots_lock);\n7 lock(cpu_hotplug_lock);\n8 sync(\u0026kvm-\u003esrcu);\n\nNote, there are likely more potential deadlocks in KVM x86, e.g. the same\npattern of taking cpu_hotplug_lock outside of kvm_lock likely exists with\n__kvmclock_cpufreq_notifier():\n\n cpuhp_cpufreq_online()\n |\n -\u003e cpufreq_online()\n |\n -\u003e cpufreq_gov_performance_limits()\n |\n -\u003e __cpufreq_driver_target()\n |\n -\u003e __target_index()\n |\n -\u003e cpufreq_freq_transition_begin()\n |\n -\u003e cpufreq_notify_transition()\n |\n -\u003e ... __kvmclock_cpufreq_notifier()\n\nBut, actually triggering such deadlocks is beyond rare due to the\ncombination of dependencies and timings involved. E.g. the cpufreq\nnotifier is only used on older CPUs without a constant TSC, mucking with\nthe NX hugepage mitigation while VMs are running is very uncommon, and\ndoing so while also onlining/offlining a CPU (necessary to generate\ncontention on cpu_hotplug_lock) would be even more unusual.\n\nThe most robust solution to the general cpu_hotplug_lock issue is likely\nto switch vm_list to be an RCU-protected list, e.g. so that x86\u0027s cpufreq\nnotifier doesn\u0027t to take kvm_lock. For now, settle for fixing the most\nblatant deadlock, as switching to an RCU-protected list is a much more\ninvolved change, but add a comment in locking.rst to call out that care\nneeds to be taken when walking holding kvm_lock and walking vm_list.\n\n ======================================================\n WARNING: possible circular locking dependency detected\n 6.10.0-smp--c257535a0c9d-pip #330 Tainted: G S O\n ------------------------------------------------------\n tee/35048 is trying to acquire lock:\n ff6a80eced71e0a8 (\u0026kvm-\u003eslots_lock){+.+.}-{3:3}, at: set_nx_huge_pages+0x179/0x1e0 [kvm]\n\n but task is already holding lock:\n ffffffffc07abb08 (kvm_lock){+.+.}-{3:3}, at: set_nx_huge_pages+0x14a/0x1e0 [kvm]\n\n which lock already depends on the new lock.\n\n the existing dependency chain (in reverse order) is:\n\n -\u003e #3 (kvm_lock){+.+.}-{3:3}:\n __mutex_lock+0x6a/0xb40\n mutex_lock_nested+0x1f/0x30\n kvm_dev_ioctl+0x4fb/0xe50 [kvm]\n __se_sys_ioctl+0x7b/0xd0\n __x64_sys_ioctl+0x21/0x30\n x64_sys_call+0x15d0/0x2e60\n do_syscall_64+0x83/0x160\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\n -\u003e #2 (cpu_hotplug_lock){++++}-{0:0}:\n cpus_read_lock+0x2e/0xb0\n static_key_slow_inc+0x16/0x30\n kvm_lapic_set_base+0x6a/0x1c0 [kvm]\n kvm_set_apic_base+0x8f/0xe0 [kvm]\n kvm_set_msr_common+0x9ae/0xf80 [kvm]\n vmx_set_msr+0xa54/0xbe0 [kvm_intel]\n __kvm_set_msr+0xb6/0x1a0 [kvm]\n kvm_arch_vcpu_ioctl+0xeca/0x10c0 [kvm]\n kvm_vcpu_ioctl+0x485/0x5b0 [kvm]\n __se_sys_ioctl+0x7b/0xd0\n __x64_sys_ioctl+0x21/0x30\n x64_sys_call+0x15d0/0x2e60\n do_syscall_64+0x83/0x160\n entry_SYSCALL_64_after_hwframe+0x76/0x7e\n\n -\u003e #1 (\u0026kvm-\u003esrcu){.+.+}-{0:0}:\n __synchronize_srcu+0x44/0x1a0\n \n---truncated---"

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: i2c: ar0521: Use cansleep version of gpiod_set_value()
If we use GPIO reset from I2C port expander, we must use *_cansleep()
variant of GPIO functions.
This was not done in ar0521_power_on()/ar0521_power_off() functions.
Let's fix that.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: phy: Remove LED entry from LEDs list on unregister
Commit c938ab4da0eb ("net: phy: Manual remove LEDs to ensure correct
ordering") correctly fixed a problem with using devm_ but missed
removing the LED entry from the LEDs list.
This cause kernel panic on specific scenario where the port for the PHY
is torn down and up and the kmod for the PHY is removed.
On setting the port down the first time, the assosiacted LEDs are
correctly unregistered. The associated kmod for the PHY is now removed.
The kmod is now added again and the port is now put up, the associated LED
are registered again.
On putting the port down again for the second time after these step, the
LED list now have 4 elements. With the first 2 already unregistered
previously and the 2 new one registered again.
This cause a kernel panic as the first 2 element should have been
removed.
Fix this by correctly removing the element when LED is unregistered.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Prevent tail call between progs attached to different hooks
bpf progs can be attached to kernel functions, and the attached functions
can take different parameters or return different return values. If
prog attached to one kernel function tail calls prog attached to another
kernel function, the ctx access or return value verification could be
bypassed.
For example, if prog1 is attached to func1 which takes only 1 parameter
and prog2 is attached to func2 which takes two parameters. Since verifier
assumes the bpf ctx passed to prog2 is constructed based on func2's
prototype, verifier allows prog2 to access the second parameter from
the bpf ctx passed to it. The problem is that verifier does not prevent
prog1 from passing its bpf ctx to prog2 via tail call. In this case,
the bpf ctx passed to prog2 is constructed from func1 instead of func2,
that is, the assumption for ctx access verification is bypassed.
Another example, if BPF LSM prog1 is attached to hook file_alloc_security,
and BPF LSM prog2 is attached to hook bpf_lsm_audit_rule_known. Verifier
knows the return value rules for these two hooks, e.g. it is legal for
bpf_lsm_audit_rule_known to return positive number 1, and it is illegal
for file_alloc_security to return positive number. So verifier allows
prog2 to return positive number 1, but does not allow prog1 to return
positive number. The problem is that verifier does not prevent prog1
from calling prog2 via tail call. In this case, prog2's return value 1
will be used as the return value for prog1's hook file_alloc_security.
That is, the return value rule is bypassed.
This patch adds restriction for tail call to prevent such bypasses.

Summary
In the Linux kernel, the following vulnerability has been resolved:
parport: Proper fix for array out-of-bounds access
The recent fix for array out-of-bounds accesses replaced sprintf()
calls blindly with snprintf(). However, since snprintf() returns the
would-be-printed size, not the actually output size, the length
calculation can still go over the given limit.
Use scnprintf() instead of snprintf(), which returns the actually
output letters, for addressing the potential out-of-bounds access
properly.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: avoid NULL pointer dereference
iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta
pointer is not NULL.
It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is
dereferencing the ieee80211_sta pointer.
If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL
pointer.
Fix this by checking the sta pointer before retrieving the mvmsta
from it. If sta is not NULL, then mvmsta isn't either.

Summary
In the Linux kernel, the following vulnerability has been resolved:
phy: mdio: fix memory leak
Syzbot reported memory leak in MDIO bus interface, the problem was in
wrong state logic.
MDIOBUS_ALLOCATED indicates 2 states:
1. Bus is only allocated
2. Bus allocated and __mdiobus_register() fails, but
device_register() was called
In case of device_register() has been called we should call put_device()
to correctly free the memory allocated for this device, but mdiobus_free()
calls just kfree(dev) in case of MDIOBUS_ALLOCATED state
To avoid this behaviour we need to set bus->state to MDIOBUS_UNREGISTERED
_before_ calling device_register(), because put_device() should be
called even in case of device_register() failure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Disable DMCUB timeout for DCN35
[Why]
DMCUB can intermittently take longer than expected to process commands.
Old ASIC policy was to continue while logging a diagnostic error - which
works fine for ASIC without IPS, but with IPS this could lead to a race
condition where we attempt to access DCN state while it's inaccessible,
leading to a system hang when the NIU port is not disabled or register
accesses that timeout and the display configuration in an undefined
state.
[How]
We need to investigate why these accesses take longer than expected, but
for now we should disable the timeout on DCN35 to avoid this race
condition. Since the waits happen only at lower interrupt levels the
risk of taking too long at higher IRQ and causing a system watchdog
timeout are minimal.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix array out-of-bound access in SoC stats
Currently, the ath11k_soc_dp_stats::hal_reo_error array is defined with a
maximum size of DP_REO_DST_RING_MAX. However, the ath11k_dp_process_rx()
function access ath11k_soc_dp_stats::hal_reo_error using the REO
destination SRNG ring ID, which is incorrect. SRNG ring ID differ from
normal ring ID, and this usage leads to out-of-bounds array access. To fix
this issue, modify ath11k_dp_process_rx() to use the normal ring ID
directly instead of the SRNG ring ID to avoid out-of-bounds array access.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: fix oops on non-dbdc mt7986
mt7915_band_config() sets band_idx = 1 on the main phy for mt7986
with MT7975_ONE_ADIE or MT7976_ONE_ADIE.
Commit 0335c034e726 ("wifi: mt76: fix race condition related to
checking tx queue fill status") introduced a dereference of the
phys array indirectly indexed by band_idx via wcid->phy_idx in
mt76_wcid_cleanup(). This caused the following Oops on affected
mt7986 devices:
Unable to handle kernel read from unreadable memory at virtual address 0000000000000024
Mem abort info:
ESR = 0x0000000096000005

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Check null pointers before using dc->clk_mgr
[WHY & HOW]
dc->clk_mgr is null checked previously in the same function, indicating
it might be null.
Passing "dc" to "dc->hwss.apply_idle_power_optimizations", which
dereferences null "dc->clk_mgr". (The function pointer resolves to
"dcn35_apply_idle_power_optimizations".)
This fixes 1 FORWARD_NULL issue reported by Coverity.

Summary
In the Linux kernel, the following vulnerability has been resolved:
iommu/vt-d: Fix PCI device refcount leak in has_external_pci()
for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.
If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() before 'return true' to avoid reference count leak.

Summary
In the Linux kernel, the following vulnerability has been resolved:
x86/hyperv: fix kexec crash due to VP assist page corruption
commit 9636be85cc5b ("x86/hyperv: Fix hyperv_pcpu_input_arg handling when
CPUs go online/offline") introduces a new cpuhp state for hyperv
initialization.
cpuhp_setup_state() returns the state number if state is
CPUHP_AP_ONLINE_DYN or CPUHP_BP_PREPARE_DYN and 0 for all other states.
For the hyperv case, since a new cpuhp state was introduced it would
return 0. However, in hv_machine_shutdown(), the cpuhp_remove_state() call
is conditioned upon "hyperv_init_cpuhp > 0". This will never be true and
so hv_cpu_die() won't be called on all CPUs. This means the VP assist page
won't be reset. When the kexec kernel tries to setup the VP assist page
again, the hypervisor corrupts the memory region of the old VP assist page
causing a panic in case the kexec kernel is using that memory elsewhere.
This was originally fixed in commit dfe94d4086e4 ("x86/hyperv: Fix kexec
panic/hang issues").
Get rid of hyperv_init_cpuhp entirely since we are no longer using a
dynamic cpuhp state and use CPUHP_AP_HYPERV_ONLINE directly with
cpuhp_remove_state().

Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/cxgb4: Added NULL check for lookup_atid
The lookup_atid() function can return NULL if the ATID is
invalid or does not exist in the identifier table, which
could lead to dereferencing a null pointer without a
check in the `act_establish()` and `act_open_rpl()` functions.
Add a NULL check to prevent null pointer dereferencing.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix a race between socket set up and I/O thread creation
In rxrpc_open_socket(), it sets up the socket and then sets up the I/O
thread that will handle it. This is a problem, however, as there's a gap
between the two phases in which a packet may come into rxrpc_encap_rcv()
from the UDP packet but we oops when trying to wake the not-yet created I/O
thread.
As a quick fix, just make rxrpc_encap_rcv() discard the packet if there's
no I/O thread yet.
A better, but more intrusive fix would perhaps be to rearrange things such
that the socket creation is done by the I/O thread.

Summary
In the Linux kernel, the following vulnerability has been resolved:
bonding: change ipsec_lock from spin lock to mutex
In the cited commit, bond->ipsec_lock is added to protect ipsec_list,
hence xdo_dev_state_add and xdo_dev_state_delete are called inside
this lock. As ipsec_lock is a spin lock and such xfrmdev ops may sleep,
"scheduling while atomic" will be triggered when changing bond's
active slave.

As bond_ipsec_add_sa_all and bond_ipsec_del_sa_all are only called
from bond_change_active_slave, which requires holding the RTNL lock.
And bond_ipsec_add_sa and bond_ipsec_del_sa are xfrm state
xdo_dev_state_add and xdo_dev_state_delete APIs, which are in user
context. So ipsec_lock doesn't have to be spin lock, change it to
mutex, and thus the above issue can be resolved.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: bcm: Clear bo->bcm_proc_read after remove_proc_entry().
syzbot reported a warning in bcm_release(). [0]
The blamed change fixed another warning that is triggered when
connect() is issued again for a socket whose connect()ed device has
been unregistered.
However, if the socket is just close()d without the 2nd connect(), the
remaining bo->bcm_proc_read triggers unnecessary remove_proc_entry()
in bcm_release().
Let's clear bo->bcm_proc_read after remove_proc_entry() in bcm_notify().

Summary
In the Linux kernel, the following vulnerability has been resolved:
rcu-tasks: Fix show_rcu_tasks_trace_gp_kthread buffer overflow
There is a possibility of buffer overflow in
show_rcu_tasks_trace_gp_kthread() if counters, passed
to sprintf() are huge. Counter numbers, needed for this
are unrealistically high, but buffer overflow is still
possible.
Use snprintf() with buffer size instead of sprintf().
Found by Linux Verification Center (linuxtesting.org) with SVACE.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix index out of bounds in DCN30 color transformation
This commit addresses a potential index out of bounds issue in the
`cm3_helper_translate_curve_to_hw_format` function in the DCN30 color
management module. The issue could occur when the index 'i' exceeds the
number of transfer function points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the
transfer function points. If 'i' is out of bounds, the function returns
false to indicate an error.
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:180 cm3_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm: call the security_mmap_file() LSM hook in remap_file_pages()
The remap_file_pages syscall handler calls do_mmap() directly, which
doesn't contain the LSM security check. And if the process has called
personality(READ_IMPLIES_EXEC) before and remap_file_pages() is called for
RW pages, this will actually result in remapping the pages to RWX,
bypassing a W^X policy enforced by SELinux.
So we should check prot by security_mmap_file LSM hook in the
remap_file_pages syscall handler before do_mmap() is called. Otherwise, it
potentially permits an attacker to bypass a W^X policy enforced by
SELinux.
The bypass is similar to CVE-2016-10044, which bypass the same thing via
AIO and can be found in [1].
The PoC:
$ cat > test.c
int main(void) {
size_t pagesz = sysconf(_SC_PAGE_SIZE);
int mfd = syscall(SYS_memfd_create, "test", 0);
const char *buf = mmap(NULL, 4 * pagesz, PROT_READ | PROT_WRITE,
MAP_SHARED, mfd, 0);
unsigned int old = syscall(SYS_personality, 0xffffffff);
syscall(SYS_personality, READ_IMPLIES_EXEC | old);
syscall(SYS_remap_file_pages, buf, pagesz, 0, 2, 0);
syscall(SYS_personality, old);
// show the RWX page exists even if W^X policy is enforced
int fd = open("/proc/self/maps", O_RDONLY);
unsigned char buf2[1024];
while (1) {
int ret = read(fd, buf2, 1024);
if (ret <= 0) break;
write(1, buf2, ret);
}
close(fd);
}
$ gcc test.c -o test
$ ./test | grep rwx

Summary
In the Linux kernel, the following vulnerability has been resolved:
ntb: ntb_hw_switchtec: Fix use after free vulnerability in switchtec_ntb_remove due to race condition
In the switchtec_ntb_add function, it can call switchtec_ntb_init_sndev
function, then &sndev->check_link_status_work is bound with
check_link_status_work. switchtec_ntb_link_notification may be called
to start the work.
If we remove the module which will call switchtec_ntb_remove to make
cleanup, it will free sndev through kfree(sndev), while the work
mentioned above will be used. The sequence of operations that may lead
to a UAF bug is as follows:
CPU0 CPU1
| check_link_status_work
switchtec_ntb_remove |
kfree(sndev); |
| if (sndev->link_force_down)
| // use sndev
Fix it by ensuring that the work is canceled before proceeding with
the cleanup in switchtec_ntb_remove.

In of_mdiobus_register_device(), we increase fwnode refcount
by fwnode_handle_get() before associating the of_node with
mdio device, but it has never been decreased in normal path.
Since that, in mdio_device_release(), it needs to call
fwnode_handle_put() in addition instead of calling kfree()
directly.
After above, just calling mdio_device_free() in the error handle
path of of_mdiobus_register_device() is enough to keep the
refcount balanced.

Summary
In the Linux kernel, the following vulnerability has been resolved:
block: fix potential invalid pointer dereference in blk_add_partition
The blk_add_partition() function initially used a single if-condition
(IS_ERR(part)) to check for errors when adding a partition. This was
modified to handle the specific case of -ENXIO separately, allowing the
function to proceed without logging the error in this case. However,
this change unintentionally left a path where md_autodetect_dev()
could be called without confirming that part is a valid pointer.
This commit separates the error handling logic by splitting the
initial if-condition, improving code readability and handling specific
error scenarios explicitly. The function now distinguishes the general
error case from -ENXIO without altering the existing behavior of
md_autodetect_dev() calls.

Summary
In the Linux kernel, the following vulnerability has been resolved:
e100: Fix possible use after free in e100_xmit_prepare
In e100_xmit_prepare(), if we can't map the skb, then return -ENOMEM, so
e100_xmit_frame() will return NETDEV_TX_BUSY and the upper layer will
resend the skb. But the skb is already freed, which will cause UAF bug
when the upper layer resends the skb.
Remove the harmful free.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: fix timer use-after-free on failed mount
Syzbot has found an ODEBUG bug in ext4_fill_super
The del_timer_sync function cancels the s_err_report timer,
which reminds about filesystem errors daily. We should
guarantee the timer is no longer active before kfree(sbi).
When filesystem mounting fails, the flow goes to failed_mount3,
where an error occurs when ext4_stop_mmpd is called, causing
a read I/O failure. This triggers the ext4_handle_error function
that ultimately re-arms the timer,
leaving the s_err_report timer active before kfree(sbi) is called.
Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd.

Summary
In the Linux kernel, the following vulnerability has been resolved:
idpf: fix UAFs when destroying the queues
The second tagged commit started sometimes (very rarely, but possible)
throwing WARNs from
net/core/page_pool.c:page_pool_disable_direct_recycling().
Turned out idpf frees interrupt vectors with embedded NAPIs *before*
freeing the queues making page_pools' NAPI pointers lead to freed
memory before these pools are destroyed by libeth.
It's not clear whether there are other accesses to the freed vectors
when destroying the queues, but anyway, we usually free queue/interrupt
vectors only when the queues are destroyed and the NAPIs are guaranteed
to not be referenced anywhere.
Invert the allocation and freeing logic making queue/interrupt vectors
be allocated first and freed last. Vectors don't require queues to be
present, so this is safe. Additionally, this change allows to remove
that useless queue->q_vector pointer cleanup, as vectors are still
valid when freeing the queues (+ both are freed within one function,
so it's not clear why nullify the pointers at all).

Summary
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix use-after-free in bpf_uprobe_multi_link_attach()
If bpf_link_prime() fails, bpf_uprobe_multi_link_attach() goes to the
error_free label and frees the array of bpf_uprobe's without calling
bpf_uprobe_unregister().
This leaks bpf_uprobe->uprobe and worse, this frees bpf_uprobe->consumer
without removing it from the uprobe->consumers list.

Summary
In the Linux kernel, the following vulnerability has been resolved:
xhci: tegra: fix checked USB2 port number
If USB virtualizatoin is enabled, USB2 ports are shared between all
Virtual Functions. The USB2 port number owned by an USB2 root hub in
a Virtual Function may be less than total USB2 phy number supported
by the Tegra XUSB controller.
Using total USB2 phy number as port number to check all PORTSC values
would cause invalid memory access.

Summary
In the Linux kernel, the following vulnerability has been resolved:
thermal: core: Reference count the zone in thermal_zone_get_by_id()
There are places in the thermal netlink code where nothing prevents
the thermal zone object from going away while being accessed after it
has been returned by thermal_zone_get_by_id().
To address this, make thermal_zone_get_by_id() get a reference on the
thermal zone device object to be returned with the help of get_device(),
under thermal_list_lock, and adjust all of its callers to this change
with the help of the cleanup.h infrastructure.

Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: fnic: Move flush_work initialization out of if block
After commit 379a58caa199 ("scsi: fnic: Move fnic_fnic_flush_tx() to a
work queue"), it can happen that a work item is sent to an uninitialized
work queue. This may has the effect that the item being queued is never
actually queued, and any further actions depending on it will not
proceed.
The following warning is observed while the fnic driver is loaded:
kernel: WARNING: CPU: 11 PID: 0 at ../kernel/workqueue.c:1524 __queue_work+0x373/0x410
kernel: <IRQ>
kernel: queue_work_on+0x3a/0x50

kernel: handle_edge_irq+0x7e/0x1a0
kernel: __common_interrupt+0x3b/0xb0
kernel: common_interrupt+0x58/0xa0
kernel: </IRQ>
It has been observed that this may break the rediscovery of Fibre
Channel devices after a temporary fabric failure.
This patch fixes it by moving the work queue initialization out of
an if block in fnic_probe().

Summary
In the Linux kernel, the following vulnerability has been resolved:
mailbox: bcm2835: Fix timeout during suspend mode
During noirq suspend phase the Raspberry Pi power driver suffer of
firmware property timeouts. The reason is that the IRQ of the underlying
BCM2835 mailbox is disabled and rpi_firmware_property_list() will always
run into a timeout [1].
Since the VideoCore side isn't consider as a wakeup source, set the
IRQF_NO_SUSPEND flag for the mailbox IRQ in order to keep it enabled
during suspend-resume cycle.

Summary
In the Linux kernel, the following vulnerability has been resolved:
media: venus: fix use after free bug in venus_remove due to race condition
in venus_probe, core->work is bound with venus_sys_error_handler, which is
used to handle error. The code use core->sys_err_done to make sync work.
The core->work is started in venus_event_notify.
If we call venus_remove, there might be an unfished work. The possible
sequence is as follows:
CPU0 CPU1
|venus_sys_error_handler
venus_remove |
hfi_destroy |
venus_hfi_destroy |
kfree(hdev); |
|hfi_reinit
|venus_hfi_queues_reinit
|//use hdev
Fix it by canceling the work in venus_remove.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ELF: fix kernel.randomize_va_space double read
ELF loader uses "randomize_va_space" twice. It is sysctl and can change
at any moment, so 2 loads could see 2 different values in theory with
unpredictable consequences.
Issue exactly one load for consistent value across one exec.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Correct the defined value for AMDGPU_DMUB_NOTIFICATION_MAX
[Why & How]
It actually exposes '6' types in enum dmub_notification_type. Not 5. Using smaller
number to create array dmub_callback & dmub_thread_offload has potential to access
item out of array bound. Fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: avoid to add interface to list twice when SER
If SER L2 occurs during the WoWLAN resume flow, the add interface flow
is triggered by ieee80211_reconfig(). However, due to
rtw89_wow_resume() return failure, it will cause the add interface flow
to be executed again, resulting in a double add list and causing a kernel
panic. Therefore, we have added a check to prevent double adding of the
list.
list_add double add: new=ffff99d6992e2010, prev=ffff99d6992e2010, next=ffff99d695302628.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk_iocost: fix more out of bound shifts
Recently running UBSAN caught few out of bound shifts in the
ioc_forgive_debts() function:
UBSAN: shift-out-of-bounds in block/blk-iocost.c:2142:38
shift exponent 80 is too large for 64-bit type 'u64' (aka 'unsigned long
long')
...
UBSAN: shift-out-of-bounds in block/blk-iocost.c:2144:30
shift exponent 80 is too large for 64-bit type 'u64' (aka 'unsigned long
long')
...
Call Trace:
<IRQ>
dump_stack_lvl+0xca/0x130
__ubsan_handle_shift_out_of_bounds+0x22c/0x280
? __lock_acquire+0x6441/0x7c10

? blk_iocost_init+0x720/0x720
__run_timer_base+0x519/0x700
...
Actual impact of this issue was not identified but I propose to fix the
undefined behaviour.
The proposed fix to prevent those out of bound shifts consist of
precalculating exponent before using it the shift operations by taking
min value from the actual exponent and maximum possible number of bits.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix bridge mode operations when there are no VFs
Currently, trying to set the bridge mode attribute when numvfs=0 leads to a
crash:

(esw->fdb_table.legacy.vepa_fdb is null)
The bridge mode is only relevant when there are multiple functions per
port. Therefore, prevent setting and getting this setting when there are no
VFs.
Note that after this change, there are no settings to change on the PF
interface using `bridge link` when there are no VFs, so the interface no
longer appears in the `bridge link` output.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ACPI: PAD: fix crash in exit_round_robin()
The kernel occasionally crashes in cpumask_clear_cpu(), which is called
within exit_round_robin(), because when executing clear_bit(nr, addr) with
nr set to 0xffffffff, the address calculation may cause misalignment within
the memory, leading to access to an invalid memory address.

cpumask_clear_cpu() in exit_round_robin(), just as it is done in
round_robin_cpu().

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix array out-of-bound access in SoC stats
Currently, the ath12k_soc_dp_stats::hal_reo_error array is defined with a
maximum size of DP_REO_DST_RING_MAX. However, the ath12k_dp_rx_process()
function access ath12k_soc_dp_stats::hal_reo_error using the REO
destination SRNG ring ID, which is incorrect. SRNG ring ID differ from
normal ring ID, and this usage leads to out-of-bounds array access. To
fix this issue, modify ath12k_dp_rx_process() to use the normal ring ID
directly instead of the SRNG ring ID to avoid out-of-bounds array access.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

CWE
- CWE-416 - Use After Free
Summary
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: taprio: extend minimum interval restriction to entire cycle too
It is possible for syzbot to side-step the restriction imposed by the
blamed commit in the Fixes: tag, because the taprio UAPI permits a
cycle-time different from (and potentially shorter than) the sum of
entry intervals.
We need one more restriction, which is that the cycle time itself must
be larger than N * ETH_ZLEN bit times, where N is the number of schedule
entries. This restriction needs to apply regardless of whether the cycle
time came from the user or was the implicit, auto-calculated value, so
we move the existing "cycle == 0" check outside the "if "(!new->cycle_time)"
branch. This way covers both conditions and scenarios.
Add a selftest which illustrates the issue triggered by syzbot.

Summary
In the Linux kernel, the following vulnerability has been resolved:
lib/generic-radix-tree.c: Fix rare race in __genradix_ptr_alloc()
If we need to increase the tree depth, allocate a new node, and then
race with another thread that increased the tree depth before us, we'll
still have a preallocated node that might be used later.
If we then use that node for a new non-root node, it'll still have a
pointer to the old root instead of being zeroed - fix this by zeroing it
in the cmpxchg failure path.

Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: don't use rate mask for offchannel TX either
Like the commit ab9177d83c04 ("wifi: mac80211: don't use rate mask for
scanning"), ignore incorrect settings to avoid no supported rate warning
reported by syzbot.
The syzbot did bisect and found cause is commit 9df66d5b9f45 ("cfg80211:
fix default HE tx bitrate mask in 2G band"), which however corrects
bitmask of HE MCS and recognizes correctly settings of empty legacy rate
plus HE MCS rate instead of returning -EINVAL.
As suggestions [1], follow the change of SCAN TX to consider this case of
offchannel TX as well.

Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/filemap: skip to create PMD-sized page cache if needed
On ARM64, HPAGE_PMD_ORDER is 13 when the base page size is 64KB. The
PMD-sized page cache can't be supported by xarray as the following error
messages indicate.

Fix it by skipping to allocate PMD-sized page cache when its size is
larger than MAX_PAGECACHE_ORDER. For this specific case, we will fall to
regular path where the readahead window is determined by BDI's sysfs file
(read_ahead_kb).

Summary
In the Linux kernel, the following vulnerability has been resolved:
net/xen-netback: prevent UAF in xenvif_flush_hash()
During the list_for_each_entry_rcu iteration call of xenvif_flush_hash,
kfree_rcu does not exist inside the rcu read critical section, so if
kfree_rcu is called when the rcu grace period ends during the iteration,
UAF occurs when accessing head->next after the entry becomes free.
Therefore, to solve this, you need to change it to list_for_each_entry_safe.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: Fix ali_drw_pmu driver interrupt status clearing
The alibaba_uncore_pmu driver forgot to clear all interrupt status
in the interrupt processing function. After the PMU counter overflow
interrupt occurred, an interrupt storm occurred, causing the system
to hang.
Therefore, clear the correct interrupt status in the interrupt handling
function to fix it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix potential null-ptr-deref in nilfs_btree_insert()
Patch series "nilfs2: fix potential issues with empty b-tree nodes".
This series addresses three potential issues with empty b-tree nodes that
can occur with corrupted filesystem images, including one recently
discovered by syzbot.
This patch (of 3):
If a b-tree is broken on the device, and the b-tree height is greater than
2 (the level of the root node is greater than 1) even if the number of
child nodes of the b-tree root is 0, a NULL pointer dereference occurs in
nilfs_btree_prepare_insert(), which is called from nilfs_btree_insert().
This is because, when the number of child nodes of the b-tree root is 0,
nilfs_btree_do_lookup() does not set the block buffer head in any of
path[x].bp_bh, leaving it as the initial value of NULL, but if the level
of the b-tree root node is greater than 1, nilfs_btree_get_nonroot_node(),
which accesses the buffer memory of path[x].bp_bh, is called.
Fix this issue by adding a check to nilfs_btree_root_broken(), which
performs sanity checks when reading the root node from the device, to
detect this inconsistency.
Thanks to Lizhi Xu for trying to solve the bug and clarifying the cause
early on.

Summary
In the Linux kernel, the following vulnerability has been resolved:
igb: Initialize mailbox message for VF reset
When a MAC address is not assigned to the VF, that portion of the message
sent to the VF is not set. The memory, however, is allocated from the
stack meaning that information may be leaked to the VM. Initialize the
message buffer to 0 so that no information is passed to the VM in this
case.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func
This commit adds a null check for the set_output_gamma function pointer
in the dcn32_set_output_transfer_func function. Previously,
set_output_gamma was being checked for null, but then it was being
dereferenced without any null check. This could lead to a null pointer
dereference if set_output_gamma is null.
To fix this, we now ensure that set_output_gamma is not null before
dereferencing it. We do this by adding a null check for set_output_gamma
before the call to set_output_gamma.

Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix hang during unmount when stopping a space reclaim worker
Often when running generic/562 from fstests we can hang during unmount,
resulting in a trace like this:

What happens is the following:
1) The cleaner kthread tries to start a transaction to delete an unused
block group, but the metadata reservation can not be satisfied right
away, so a reservation ticket is created and it starts the async
metadata reclaim task (fs_info->async_reclaim_work);
2) Writeback for all the filler inodes with an i_size of 2K starts
(generic/562 creates a lot of 2K files with the goal of filling
metadata space). We try to create an inline extent for them, but we
fail when trying to insert the inline extent with -ENOSPC (at
cow_file_range_inline()) - since this is not critical, we fallback
to non-inline mode (back to cow_file_range()), reserve extents

Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: health: afe4403: Fix oob read in afe4403_read_raw
KASAN report out-of-bounds read as follows:
BUG: KASAN: global-out-of-bounds in afe4403_read_raw+0x42e/0x4c0
Read of size 4 at addr ffffffffc02ac638 by task cat/279
Call Trace:
afe4403_read_raw
iio_read_channel_info
dev_attr_show
The buggy address belongs to the variable:
afe4403_channel_leds+0x18/0xffffffffffffe9e0
This issue can be reproduced by singe command:
$ cat /sys/bus/spi/devices/spi0.0/iio\:device0/in_intensity6_raw
The array size of afe4403_channel_leds is less than channels, so access
with chan->address cause OOB read in afe4403_read_raw. Fix it by moving
access before use it.

Summary
In the Linux kernel, the following vulnerability has been resolved:
rtc: cmos: Fix event handler registration ordering issue
Because acpi_install_fixed_event_handler() enables the event
automatically on success, it is incorrect to call it before the
handler routine passed to it is ready to handle events.
Unfortunately, the rtc-cmos driver does exactly the incorrect thing
by calling cmos_wake_setup(), which passes rtc_handler() to
acpi_install_fixed_event_handler(), before cmos_do_probe(), because
rtc_handler() uses dev_get_drvdata() to get to the cmos object
pointer and the driver data pointer is only populated in
cmos_do_probe().
This leads to a NULL pointer dereference in rtc_handler() on boot
if the RTC fixed event happens to be active at the init time.
To address this issue, change the initialization ordering of the
driver so that cmos_wake_setup() is always called after a successful
cmos_do_probe() call.
While at it, change cmos_pnp_probe() to call cmos_do_probe() after
the initial if () statement used for computing the IRQ argument to
be passed to cmos_do_probe() which is cleaner than calling it in
each branch of that if () (local variable "irq" can be of type int,
because it is passed to that function as an argument of type int).
Note that commit 6492fed7d8c9 ("rtc: rtc-cmos: Do not check
ACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger number
of systems, because previously it only affected systems with
ACPI_FADT_LOW_POWER_S0 set, but it is present regardless of that
commit.

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tun: Fix use-after-free in tun_detach()
syzbot reported use-after-free in tun_detach() [1]. This causes call
trace like below:
==================================================================

The cause of the issue is that sock_put() from __tun_detach() drops
last reference count for struct net, and then notifier_call_chain()
from netdev_state_change() accesses that struct net.
This patch fixes the issue by calling sock_put() from tun_detach()
after all necessary accesses for the struct net has done.

Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: re-fetch skb cb after tipc_msg_validate
As the call trace shows, the original skb was freed in tipc_msg_validate(),
and dereferencing the old skb cb would cause an use-after-free crash.

Summary
In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix state management in error path of log writing function
After commit a694291a6211 ("nilfs2: separate wait function from
nilfs_segctor_write") was applied, the log writing function
nilfs_segctor_do_construct() was able to issue I/O requests continuously
even if user data blocks were split into multiple logs across segments,
but two potential flaws were introduced in its error handling.
First, if nilfs_segctor_begin_construction() fails while creating the
second or subsequent logs, the log writing function returns without
calling nilfs_segctor_abort_construction(), so the writeback flag set on
pages/folios will remain uncleared. This causes page cache operations to
hang waiting for the writeback flag. For example,
truncate_inode_pages_final(), which is called via nilfs_evict_inode() when
an inode is evicted from memory, will hang.
Second, the NILFS_I_COLLECTED flag set on normal inodes remain uncleared.
As a result, if the next log write involves checkpoint creation, that's
fine, but if a partial log write is performed that does not, inodes with
NILFS_I_COLLECTED set are erroneously removed from the "sc_dirty_files"
list, and their data and b-tree blocks may not be written to the device,
corrupting the block mapping.
Fix these issues by uniformly calling nilfs_segctor_abort_construction()
on failure of each step in the loop in nilfs_segctor_do_construct(),
having it clean up logs and segment usages according to progress, and
correcting the conditions for calling nilfs_redirty_inodes() to ensure
that the NILFS_I_COLLECTED flag is cleared.

Summary
In the Linux kernel, the following vulnerability has been resolved:
blk-mq: setup queue ->tag_set before initializing hctx
Commit 7b815817aa58 ("blk-mq: add helper for checking if one CPU is mapped to specified hctx")
needs to check queue mapping via tag set in hctx's cpuhp handler.
However, q->tag_set may not be setup yet when the cpuhp handler is
enabled, then kernel oops is triggered.
Fix the issue by setup queue tag_set before initializing hctx.

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix u8 overflow
By keep sending L2CAP_CONF_REQ packets, chan->num_conf_rsp increases
multiple times and eventually it will wrap around the maximum number
(i.e., 255).
This patch prevents this by adding a boundary check with
L2CAP_MAX_CONF_RSP

Summary
In the Linux kernel, the following vulnerability has been resolved:
static_call: Handle module init failure correctly in static_call_del_module()
Module insertion invokes static_call_add_module() to initialize the static
calls in a module. static_call_add_module() invokes __static_call_init(),
which allocates a struct static_call_mod to either encapsulate the built-in
static call sites of the associated key into it so further modules can be
added or to append the module to the module chain.
If that allocation fails the function returns with an error code and the
module core invokes static_call_del_module() to clean up eventually added
static_call_mod entries.
This works correctly, when all keys used by the module were converted over
to a module chain before the failure. If not then static_call_del_module()
causes a #GP as it blindly assumes that key::mods points to a valid struct
static_call_mod.
The problem is that key::mods is not a individual struct member of struct
static_call_key, it's part of a union to save space:
union {
/* bit 0: 0 = mods, 1 = sites */
unsigned long type;
struct static_call_mod *mods;
struct static_call_site *sites;
};
key::sites is a pointer to the list of built-in usage sites of the static
call. The type of the pointer is differentiated by bit 0. A mods pointer
has the bit clear, the sites pointer has the bit set.
As static_call_del_module() blidly assumes that the pointer is a valid
static_call_mod type, it fails to check for this failure case and
dereferences the pointer to the list of built-in call sites, which is
obviously bogus.
Cure it by checking whether the key has a sites or a mods pointer.
If it's a sites pointer then the key is not to be touched. As the sites are
walked in the same order as in __static_call_init() the site walk can be
terminated because all subsequent sites have not been touched by the init
code due to the error exit.
If it was converted before the allocation fail, then the inner loop which
searches for a module match will find nothing.
A fail in the second allocation in __static_call_init() is harmless and
does not require special treatment. The first allocation succeeded and
converted the key to a module chain. That first entry has mod::mod == NULL
and mod::next == NULL, so the inner loop of static_call_del_module() will
neither find a module match nor a module chain. The next site in the walk
was either already converted, but can't match the module, or it will exit
the outer loop because it has a static_call_site pointer and not a
static_call_mod pointer.

If not then static_call_del_module()\ncauses a #GP as it blindly assumes that key::mods points to a valid struct\nstatic_call_mod.\n\nThe problem is that key::mods is not a individual struct member of struct\nstatic_call_key, it\u0027s part of a union to save space:\n\n union {\n /* bit 0: 0 = mods, 1 = sites */\n unsigned long type;\n struct static_call_mod *mods;\n struct static_call_site *sites;\n\t};\n\nkey::sites is a pointer to the list of built-in usage sites of the static\ncall. The type of the pointer is differentiated by bit 0. A mods pointer\nhas the bit clear, the sites pointer has the bit set.\n\nAs static_call_del_module() blidly assumes that the pointer is a valid\nstatic_call_mod type, it fails to check for this failure case and\ndereferences the pointer to the list of built-in call sites, which is\nobviously bogus.\n\nCure it by checking whether the key has a sites or a mods pointer.\n\nIf it\u0027s a sites pointer then the key is not to be touched. As the sites are\nwalked in the same order as in __static_call_init() the site walk can be\nterminated because all subsequent sites have not been touched by the init\ncode due to the error exit.\n\nIf it was converted before the allocation fail, then the inner loop which\nsearches for a module match will find nothing.\n\nA fail in the second allocation in __static_call_init() is harmless and\ndoes not require special treatment. The first allocation succeeded and\nconverted the key to a module chain. That first entry has mod::mod == NULL\nand mod::next == NULL, so the inner loop of static_call_del_module() will\nneither find a module match nor a module chain. The next site in the walk\nwas either already converted, but can\u0027t match the module, or it will exit\nthe outer loop because it has a static_call_site pointer and not a\nstatic_call_mod pointer."

Summary
In the Linux kernel, the following vulnerability has been resolved:
ublk: don't allow user copy for unprivileged device
UBLK_F_USER_COPY requires userspace to call write() on ublk char
device for filling request buffer, and unprivileged device can't
be trusted.
So don't allow user copy for unprivileged device.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Avoid race between dcn10_set_drr() and dc_state_destruct()
dc_state_destruct() nulls the resource context of the DC state. The pipe
context passed to dcn10_set_drr() is a member of this resource context.
If dc_state_destruct() is called parallel to the IRQ processing (which
calls dcn10_set_drr() at some point), we can end up using already nulled
function callback fields of struct stream_resource.
The logic in dcn10_set_drr() already tries to avoid this, by checking tg
against NULL. But if the nulling happens exactly after the NULL check and
before the next access, then we get a race.
Avoid this by copying tg first to a local variable, and then use this
variable for all the operations. This should work, as long as nobody
frees the resource pool where the timing generators live.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for pipe_ctx->plane_state in dcn20_program_pipe
This commit addresses a null pointer dereference issue in the
`dcn20_program_pipe` function. The issue could occur when
`pipe_ctx->plane_state` is null.
The fix adds a check to ensure `pipe_ctx->plane_state` is not null
before accessing. This prevents a null pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn20/dcn20_hwseq.c:1925 dcn20_program_pipe() error: we previously assumed 'pipe_ctx->plane_state' could be null (see line 1877)

Summary
In the Linux kernel, the following vulnerability has been resolved:
gpio: amd8111: Fix PCI device reference count leak
for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL.
If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL
input parameter, there is no problem for the 'Device not found' branch.
For the normal path, add pci_dev_put() in amd_gpio_exit().

Summary
In the Linux kernel, the following vulnerability has been resolved:
i40e: Fix XDP program unloading while removing the driver
The commit 6533e558c650 ("i40e: Fix reset path while removing
the driver") introduced a new PF state "__I40E_IN_REMOVE" to block
modifying the XDP program while the driver is being removed.
Unfortunately, such a change is useful only if the ".ndo_bpf()"
callback was called out of the rmmod context because unloading the
existing XDP program is also a part of driver removing procedure.
In other words, from the rmmod context the driver is expected to
unload the XDP program without reporting any errors. Otherwise,
the kernel warning with callstack is printed out to dmesg.
Example failing scenario:
1. Load the i40e driver.
2. Load the XDP program.
3. Unload the i40e driver (using "rmmod" command).
The example kernel warning log:

Fix this by checking if the XDP program is being loaded or unloaded.
Then, block only loading a new program while "__I40E_IN_REMOVE" is set.
Also, move testing "__I40E_IN_REMOVE" flag to the beginning of XDP_SETUP
callback to avoid unnecessary operations and checks.

Summary
In the Linux kernel, the following vulnerability has been resolved:
ixgbevf: Fix resource leak in ixgbevf_init_module()
ixgbevf_init_module() won't destroy the workqueue created by
create_singlethread_workqueue() when pci_register_driver() failed. Add
destroy_workqueue() in fail path to prevent the resource leak.
Similar to the handling of u132_hcd_init in commit f276e002793c
("usb: u132-hcd: fix resource leak")

Summary
In the Linux kernel, the following vulnerability has been resolved:
Input: adp5589-keys - fix NULL pointer dereference
We register a devm action to call adp5589_clear_config() and then pass
the i2c client as argument so that we can call i2c_get_clientdata() in
order to get our device object. However, i2c_set_clientdata() is only
being set at the end of the probe function which means that we'll get a
NULL pointer dereference in case the probe function fails early.

Summary
In the Linux kernel, the following vulnerability has been resolved:
powerpc/qspinlock: Fix deadlock in MCS queue
If an interrupt occurs in queued_spin_lock_slowpath() after we increment
qnodesp->count and before node->lock is initialized, another CPU might
see stale lock values in get_tail_qnode(). If the stale lock value happens
to match the lock on that CPU, then we write to the "next" pointer of
the wrong qnode. This causes a deadlock as the former CPU, once it becomes
the head of the MCS queue, will spin indefinitely until it's "next" pointer
is set by its successor in the queue.
Running stress-ng on a 16 core (16EC/16VP) shared LPAR, results in
occasional lockups similar to the following:
$ stress-ng --all 128 --vm-bytes 80% --aggressive \
--maximize --oomable --verify --syslog \
--metrics --times --timeout 5m
watchdog: CPU 15 Hard LOCKUP

contended and we call the queued_spin_lock_slowpath() function.

Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add NULL check for clk_mgr and clk_mgr->funcs in dcn30_init_hw
This commit addresses a potential null pointer dereference issue in the
`dcn30_init_hw` function. The issue could occur when `dc->clk_mgr` or
`dc->clk_mgr->funcs` is null.
The fix adds a check to ensure `dc->clk_mgr` and `dc->clk_mgr->funcs` is
not null before accessing its functions. This prevents a potential null
pointer dereference.
Reported by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:789 dcn30_init_hw() error: we previously assumed 'dc->clk_mgr' could be null (see line 628)

Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Call iso_exit() on module unload
If iso_init() has been called, iso_exit() must be called on module
unload. Without that, the struct proto that iso_init() registered with
proto_register() becomes invalid, which could cause unpredictable
problems later. In my case, with CONFIG_LIST_HARDENED and
CONFIG_BUG_ON_DATA_CORRUPTION enabled, loading the module again usually
triggers this BUG():
list_add corruption. next->prev should be prev (ffffffffb5355fd0),
but was 0000000000000068. (next=ffffffffc0a010d0).

Summary
In the Linux kernel, the following vulnerability has been resolved:
net: test for not too small csum_start in virtio_net_hdr_to_skb()
syzbot was able to trigger this warning [1], after injecting a
malicious packet through af_packet, setting skb->csum_start and thus
the transport header to an incorrect value.
We can at least make sure the transport header is after
the end of the network header (with a estimated minimal size).

Summary
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: reserve space for inline xattr before attaching reflink tree
One of our customers reported a crash and a corrupted ocfs2 filesystem.
The crash was due to the detection of corruption. Upon troubleshooting,
the fsck -fn output showed the below corruption
[EXTENT_LIST_FREE] Extent list in owner 33080590 claims 230 as the next free chain record,
but fsck believes the largest valid value is 227. Clamp the next record value? n
The stat output from the debugfs.ocfs2 showed the following corruption
where the "Next Free Rec:" had overshot the "Count:" in the root metadata
block.

The issue was in the reflink workfow while reserving space for inline
xattr. The problematic function is ocfs2_reflink_xattr_inline(). By the
time this function is called the reflink tree is already recreated at the
destination inode from the source inode. At this point, this function
reserves space for inline xattrs at the destination inode without even
checking if there is space at the root metadata block. It simply reduces
the l_count from 243 to 227 thereby making space of 256 bytes for inline
xattr whereas the inode already has extents beyond this index (in this
case up to 230), thereby causing corruption.
The fix for this is to reserve space for inline metadata at the destination
inode before the reflink tree gets recreated. The customer has verified the
fix.

At this point, this function\nreserves space for inline xattrs at the destination inode without even\nchecking if there is space at the root metadata block. It simply reduces\nthe l_count from 243 to 227 thereby making space of 256 bytes for inline\nxattr whereas the inode already has extents beyond this index (in this\ncase up to 230), thereby causing corruption.\n\nThe fix for this is to reserve space for inline metadata at the destination\ninode before the reflink tree gets recreated. The customer has verified the\nfix."

...
If DAT metadata file is corrupted on disk, there is a case where
req->pr_desc_bh is NULL and blocknr is 0 at nilfs_dat_commit_end() during
a b-tree operation that cascadingly updates ancestor nodes of the b-tree,
because nilfs_dat_commit_alloc() for a lower level block can initialize
the blocknr on the same DAT entry between nilfs_dat_prepare_end() and
nilfs_dat_commit_end().
If this happens, nilfs_dat_commit_end() calls nilfs_dat_commit_free()
without valid buffer heads in req->pr_desc_bh and req->pr_bitmap_bh, and
causes the NULL pointer dereference above in
nilfs_palloc_commit_free_entry() function, which leads to a crash.
Fix this by adding a NULL check on req->pr_desc_bh and req->pr_bitmap_bh
before nilfs_palloc_commit_free_entry() in nilfs_dat_commit_free().
This also calls nilfs_error() in that case to notify that there is a fatal
flaw in the filesystem metadata and prevent further operations.

Summary
In the Linux kernel, the following vulnerability has been resolved:
can: af_can: fix NULL pointer dereference in can_rcv_filter
Analogue to commit 8aa59e355949 ("can: af_can: fix NULL pointer
dereference in can_rx_register()") we need to check for a missing
initialization of ml_priv in the receive path of CAN frames.
Since commit 4e096a18867a ("net: introduce CAN specific pointer in the
struct net_device") the check for dev->type to be ARPHRD_CAN is not
sufficient anymore since bonding or tun netdevices claim to be CAN
devices but do not initialize ml_priv accordingly.
