        Summary
An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 (netfilter: nf_tables: Reject tables of unsupported family); While creating a new netfilter table, lack of a safeguard against invalid nf_tables family (pf) values within `nf_tables_newtable` function enables an attacker to achieve out-of-bounds access.

          - CWE-416 - Use After Free
Summary
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fix possible store tearing in neigh_periodic_work()
While looking at a related syzbot report involving neigh_periodic_work(),
I found that I forgot to add an annotation when deleting an
RCU protected item from a list.
Readers use rcu_deference(*np), we need to use either
rcu_assign_pointer() or WRITE_ONCE() on writer side
to prevent store tearing.
I use rcu_assign_pointer() to have lockdep support,
this was the choice made in neigh_flush_dev().

        Summary
In the Linux kernel, the following vulnerability has been resolved:
i2c: i801: Fix block process call transactions
According to the Intel datasheets, software must reset the block
buffer index twice for block process call transactions: once before
writing the outgoing data to the buffer, and once again before
reading the incoming data from the buffer.
The driver is currently missing the second reset, causing the wrong
portion of the block buffer to be read.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
sched/membarrier: reduce the ability to hammer on sys_membarrier
On some systems, sys_membarrier can be very expensive, causing overall
slowdowns for everything.  So put a lock on the path in order to
serialize the accesses to prevent the ability for this to be called at
too high of a frequency and saturate the machine.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tls: handle backlogging of crypto requests
Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our
requests to the crypto API, crypto_aead_{encrypt,decrypt} can return
 -EBUSY instead of -EINPROGRESS in valid situations. For example, when
the cryptd queue for AESNI is full (easy to trigger with an
artificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueued
to the backlog but still processed. In that case, the async callback
will also be called twice: first with err == -EINPROGRESS, which it
seems we can just ignore, then with err == 0.
Compared to Sabrina's original patch this version uses the new
tls_*crypt_async_wait() helpers and converts the EBUSY to
EINPROGRESS to avoid having to modify all the error handling
paths. The handling is identical.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
ip6_tunnel: fix NEXTHDR_FRAGMENT handling in ip6_tnl_parse_tlv_enc_lim()
syzbot pointed out [1] that NEXTHDR_FRAGMENT handling is broken.
Reading frag_off can only be done if we pulled enough bytes
to skb->head. Currently we might access garbage.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/sparsemem: fix race in accessing memory_section->usage
The below race is observed on a PFN which falls into the device memory
region with the system memory configuration where PFN's are such that
[ZONE_NORMAL ZONE_DEVICE ZONE_NORMAL].  Since normal zone start and end
pfn contains the device memory PFN's as well, the compaction triggered
will try on the device memory PFN's too though they end up in NOP(because
pfn_to_online_page() returns NULL for ZONE_DEVICE memory sections).  When
from other core, the section mappings are being removed for the
ZONE_DEVICE region, that the PFN in question belongs to, on which
compaction is currently being operated is resulting into the kernel crash
with CONFIG_SPASEMEM_VMEMAP enabled.  The crash logs can be seen at [1].
compact_zone()			memunmap_pages
-------------			---------------
__pageblock_pfn_to_page
   ......
 (a)pfn_valid():
     valid_section()//return true
			      (b)__remove_pages()->
				  sparse_remove_section()->
				    section_deactivate():
				    [Free the array ms->usage and set
				     ms->usage = NULL]
     pfn_section_valid()
     [Access ms->usage which
     is NULL]
NOTE: From the above it can be said that the race is reduced to between
the pfn_valid()/pfn_section_valid() and the section deactivate with
SPASEMEM_VMEMAP enabled.
The commit b943f045a9af("mm/sparse: fix kernel crash with
pfn_section_valid check") tried to address the same problem by clearing
the SECTION_HAS_MEM_MAP with the expectation of valid_section() returns
false thus ms->usage is not accessed.
Fix this issue by the below steps:
a) Clear SECTION_HAS_MEM_MAP before freeing the ->usage.
b) RCU protected read side critical section will either return NULL
   when SECTION_HAS_MEM_MAP is cleared or can successfully access ->usage.
c) Free the ->usage with kfree_rcu() and set ms->usage = NULL.  No
   attempt will be made to access ->usage after this as the
   SECTION_HAS_MEM_MAP is cleared thus valid_section() return false.
Thanks to David/Pavan for their inputs on this patch.

On Snapdragon SoC, with the mentioned memory configuration of PFN's as
[ZONE_NORMAL ZONE_DEVICE ZONE_NORMAL], we are able to see bunch of
issues daily while testing on a device farm.
For this particular issue below is the log.  Though the below log is
not directly pointing to the pfn_section_valid(){ ms->usage;}, when we
loaded this dump on T32 lauterbach tool, it is pointing.

Since normal zone start and end\npfn contains the device memory PFN\u0027s as well, the compaction triggered\nwill try on the device memory PFN\u0027s too though they end up in NOP(because\npfn_to_online_page() returns NULL for ZONE_DEVICE memory sections).  When\nfrom other core, the section mappings are being removed for the\nZONE_DEVICE region, that the PFN in question belongs to, on which\ncompaction is currently being operated is resulting into the kernel crash\nwith CONFIG_SPASEMEM_VMEMAP enabled.

No\n   attempt will be made to access -\u003eusage after this as the\n   SECTION_HAS_MEM_MAP is cleared thus valid_section() return false.\n\nThanks to David/Pavan for their inputs on this patch.\n\n[1] https://lore.kernel.org/linux-mm/994410bb-89aa-d987-1f50-f514903c55aa@quicinc.com/\n\nOn Snapdragon SoC, with the mentioned memory configuration of PFN\u0027s as\n[ZONE_NORMAL ZONE_DEVICE ZONE_NORMAL], we are able to see bunch of\nissues daily while testing on a device farm.\n\nFor this particular issue below is the log.

        CWE
          - CWE-416 - Use After Free
Summary
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT.
We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660.

          - CWE-125 - Out-of-bounds Read
Summary
An out-of-bounds read vulnerability was found in the NVMe-oF/TCP subsystem in the Linux kernel. This issue may allow a remote attacker to send a crafted TCP packet, triggering a heap-based buffer overflow that results in kmalloc data being printed and potentially leaked to the kernel ring buffer (dmesg).

          - CWE-476 - NULL Pointer Dereference
Summary
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
perf/x86/lbr: Filter vsyscall addresses
We found that a panic can occur when a vsyscall is made while LBR sampling
is active. If the vsyscall is interrupted (NMI) for perf sampling, this
call sequence can occur (most recent at top):
    __insn_get_emulate_prefix()
    insn_get_emulate_prefix()
    insn_get_prefixes()
    insn_get_opcode()
    decode_branch_type()
    get_branch_type()
    intel_pmu_lbr_filter()
    intel_pmu_handle_irq()
    perf_event_nmi_handler()
Within __insn_get_emulate_prefix() at frame 0, a macro is called:
    peek_nbyte_next(insn_byte_t, insn, i)
Within this macro, this dereference occurs:
    (insn)->next_byte
Inspecting registers at this point, the value of the next_byte field is the
address of the vsyscall made, for example the location of the vsyscall
version of gettimeofday() at 0xffffffffff600000. The access to an address
in the vsyscall region will trigger an oops due to an unhandled page fault.
To fix the bug, filtering for vsyscalls can be done when
determining the branch type. This patch will return
a "none" branch if a kernel address if found to lie in the
vsyscall region.

        CWE
          - CWE-787 - Out-of-bounds Write
Summary
A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.
A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group().
We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b.

        CWE
          - CWE-416 - Use After Free
Summary
A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation.
The nft_setelem_catchall_deactivate() function checks whether the catch-all set element is active in the current generation instead of the next generation before freeing it, but only flags it inactive in the next generation, making it possible to free the element multiple times, leading to a double free vulnerability.
We recommend upgrading past commit b1db244ffd041a49ecc9618e8feb6b5c1afcdaa7.

        CWE
          - CWE-416 - Use After Free
Summary
A race condition was found in the QXL driver in the Linux kernel. The qxl_mode_dumb_create() function dereferences the qobj returned by the qxl_gem_object_create_with_handle(), but the handle is the only one holding a reference to it. This flaw allows an attacker to guess the returned handle value and trigger a use-after-free issue, potentially leading to a denial of service or privilege escalation.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between async notify and socket close
The submitting thread (one which called recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete()
so any code past that point risks touching already freed data.
Try to avoid the locking and extra flags altogether.
Have the main thread hold an extra reference, this way
we can depend solely on the atomic ref counter for
synchronization.
Don't futz with reiniting the completion, either, we are now
tightly controlling when completion fires.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.

When enslave a vlan device to team device and team device type is changed
from non-ether to ether, header_ops of team device is changed to
vlan_header_ops. That is incorrect and will trigger null-ptr-deref
for vlan->real_dev in vlan_dev_hard_header() because team device is not
a vlan device.
Cache eth_header_ops in team_setup(), then assign cached header_ops to
header_ops of team net device when its type is changed from non-ether
to ether to fix the bug.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_acl_tcam: Fix stack corruption
When tc filters are first added to a net device, the corresponding local
port gets bound to an ACL group in the device. The group contains a list
of ACLs. In turn, each ACL points to a different TCAM region where the
filters are stored. During forwarding, the ACLs are sequentially
evaluated until a match is found.
One reason to place filters in different regions is when they are added
with decreasing priorities and in an alternating order so that two
consecutive filters can never fit in the same region because of their
key usage.
In Spectrum-2 and newer ASICs the firmware started to report that the
maximum number of ACLs in a group is more than 16, but the layout of the
register that configures ACL groups (PAGT) was not updated to account
for that. It is therefore possible to hit stack corruption [1] in the
rare case where more than 16 ACLs in a group are required.
Fix by limiting the maximum ACL group size to the minimum between what
the firmware reports and the maximum ACLs that fit in the PAGT register.
Add a test case to make sure the machine does not crash when this
condition is hit.

The group contains a list\nof ACLs. In turn, each ACL points to a different TCAM region where the\nfilters are stored. During forwarding, the ACLs are sequentially\nevaluated until a match is found.\n\nOne reason to place filters in different regions is when they are added\nwith decreasing priorities and in an alternating order so that two\nconsecutive filters can never fit in the same region because of their\nkey usage.\n\nIn Spectrum-2 and newer ASICs the firmware started to report that the\nmaximum number of ACLs in a group is more than 16, but the layout of the\nregister that configures ACL groups (PAGT) was not updated to account\nfor that. It is therefore possible to hit stack corruption [1] in the\nrare case where more than 16 ACLs in a group are required.\n\nFix by limiting the maximum ACL group size to the minimum between what\nthe firmware reports and the maximum ACLs that fit in the PAGT register.\n\nAdd a test case to make sure the machine does not crash when this\ncondition is hit.\n\n[1]\nKernel panic - not syncing: stack-protector: Kernel stack is corrupted in: mlxsw_sp_acl_tcam_group_update+0x116/0x120\n[...]\n dump_stack_lvl+0x36/0x50\n panic+0x305/0x330\n __stack_chk_fail+0x15/0x20\n mlxsw_sp_acl_tcam_group_update+0x116/0x120\n mlxsw_sp_acl_tcam_group_region_attach+0x69/0x110\n mlxsw_sp_acl_tcam_vchunk_get+0x492/0xa20\n mlxsw_sp_acl_tcam_ventry_add+0x25/0xe0\n mlxsw_sp_acl_rule_add+0x47/0x240\n mlxsw_sp_flower_replace+0x1a9/0x1d0\n tc_setup_cb_add+0xdc/0x1c0\n fl_hw_replace_filter+0x146/0x1f0\n fl_change+0xc17/0x1360\n tc_new_tfilter+0x472/0xb90\n rtnetlink_rcv_msg+0x313/0x3b0\n netlink_rcv_skb+0x58/0x100\n netlink_unicast+0x244/0x390\n netlink_sendmsg+0x1e4/0x440\n ____sys_sendmsg+0x164/0x260\n ___sys_sendmsg+0x9a/0xe0\n __sys_sendmsg+0x7a/0xc0\n do_syscall_64+0x40/0xe0\n entry_SYSCALL_64_after_hwframe+0x63/0x6b"

        Summary
In the Linux kernel, the following vulnerability has been resolved:
gfs2: Fix kernel NULL pointer dereference in gfs2_rgrp_dump
Syzkaller has reported a NULL pointer dereference when accessing
rgd->rd_rgl in gfs2_rgrp_dump().  This can happen when creating
rgd->rd_gl fails in read_rindex_entry().  Add a NULL pointer check in
gfs2_rgrp_dump() to prevent that.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
net: tls: fix use-after-free with partial reads and async decrypt
tls_decrypt_sg doesn't take a reference on the pages from clear_skb,
so the put_page() in tls_decrypt_done releases them, and we trigger
a use-after-free in process_rx_list when we try to read from the
partially-read skb.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
net: bridge: use DEV_STATS_INC()
syzbot/KCSAN reported data-races in br_handle_frame_finish() [1]
This function can run from multiple cpus without mutual exclusion.
Adopt SMP safe DEV_STATS_INC() to update dev->stats fields.
Handles updates to dev->stats.tx_dropped while we are at it.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
net/core: Fix ETH_P_1588 flow dissector
When a PTP ethernet raw frame with a size of more than 256 bytes followed
by a 0xff pattern is sent to __skb_flow_dissect, nhoff value calculation
is wrong. For example: hdr->message_length takes the wrong value (0xffff)
and it does not replicate real header length. In this case, 'nhoff' value
was overridden and the PTP header was badly dissected. This leads to a
kernel crash.
net/core: flow_dissector
net/core flow dissector nhoff = 0x0000000e
net/core flow dissector hdr->message_length = 0x0000ffff
net/core flow dissector nhoff = 0x0001000d (u16 overflow)
...
skb linear:   00000000: 00 a0 c9 00 00 00 00 a0 c9 00 00 00 88
skb frag:     00000000: f7 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
Using the size of the ptp_header struct will allow the corrected
calculation of the nhoff value.
net/core flow dissector nhoff = 0x0000000e
net/core flow dissector nhoff = 0x00000030 (sizeof ptp_header)
...
skb linear:   00000000: 00 a0 c9 00 00 00 00 a0 c9 00 00 00 88 f7 ff ff
skb linear:   00000010: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff

        Summary
In the Linux kernel, the following vulnerability has been resolved:
net/sched: act_ct: fix skb leak and crash on ooo frags
act_ct adds skb->users before defragmentation. If frags arrive in order,
the last frag's reference is reset in:
  inet_frag_reasm_prepare
    skb_morph
which is not straightforward.
However when frags arrive out of order, nobody unref the last frag, and
all frags are leaked. The situation is even worse, as initiating packet
capture can lead to a crash[0] when skb has been cloned and shared at the
same time.
Fix the issue by removing skb_get() before defragmentation. act_ct
returns TC_ACT_CONSUMED when defrag failed or in progress.

          - CWE-416 - Use After Free
Summary
A use-after-free vulnerability in the Linux kernel's ipv4: igmp component can be exploited to achieve local privilege escalation.
A race condition can be exploited to cause a timer be mistakenly registered on a RCU read locked object which is freed by another thread.
We recommend upgrading past commit e2b706c691905fe78468c361aaabc719d0a496f1.

        Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: fix memleak when more than 255 elements expired
When more than 255 elements expired we're supposed to switch to a new gc
container structure.
This never happens: u8 type will wrap before reaching the boundary
and nft_trans_gc_space() always returns true.
This means we recycle the initial gc container structure and
lose track of the elements that came before.
While at it, don't deref 'gc' after we've passed it to call_rcu.
