CVE-2022-48986 (GCVE-0-2022-48986)

Title
mm/gup: fix gup_pud_range() for dax
Summary
In the Linux kernel, the following vulnerability has been resolved:
mm/gup: fix gup_pud_range() for dax
For dax pud, pud_huge() returns true on x86. So the function works as long
as hugetlb is configured. However, dax doesn't depend on hugetlb.
Commit 414fd080d125 ("mm/gup: fix gup_pmd_range() for dax") fixed
devmap-backed huge PMDs, but missed devmap-backed huge PUDs. Fix this as
well.
This fixes the below kernel panic:
general protection fault, probably for non-canonical address 0x69e7c000cc478: 0000 [#1] SMP

Title
netfilter: use get_random_u32 instead of prandom
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: use get_random_u32 instead of prandom
bh might occur while updating per-cpu rnd_state from user context,
ie. local_out path.
BUG: using smp_processor_id() in preemptible [00000000] code: nginx/2725
caller is nft_ng_random_eval+0x24/0x54 [nft_numgen]
Call Trace:
check_preemption_disabled+0xde/0xe0
nft_ng_random_eval+0x24/0x54 [nft_numgen]
Use the random driver instead, this also avoids need for local prandom
state. Moreover, prandom now uses the random driver since d4150779e60f
("random32: use real rng for non-deterministic randomness").
Based on earlier patch from Pablo Neira.
Severity
No CVSS data available.

Title
media: v4l2-tpg: fix some memleaks in tpg_alloc
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-tpg: fix some memleaks in tpg_alloc
In tpg_alloc, resources should be deallocated in each and every
error-handling paths, since they are allocated in for statements.
Otherwise there would be memleaks because tpg_free is called only when
tpg_alloc return 0.
Severity
No CVSS data available.

Title
jbd2: stop waiting for space when jbd2_cleanup_journal_tail() returns error
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.

Title
posix-clock: Fix missing timespec64 check in pc_clock_settime()
Summary
In the Linux kernel, the following vulnerability has been resolved:
posix-clock: Fix missing timespec64 check in pc_clock_settime()
As Andrew pointed out, it will make sense that the PTP core
checked timespec64 struct's tv_sec and tv_nsec range before calling
ptp->info->settime64().
As the man manual of clock_settime() said, if tp.tv_sec is negative or
tp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL,
which include dynamic clocks which handles PTP clock, and the condition is
consistent with timespec64_valid(). As Thomas suggested, timespec64_valid()
only check the timespec is valid, but not ensure that the time is
in a valid range, so check it ahead using timespec64_valid_strict()
in pc_clock_settime() and return -EINVAL if not valid.
There are some drivers that use tp->tv_sec and tp->tv_nsec directly to
write registers without validity checks and assume that the higher layer
has checked it, which is dangerous and will benefit from this, such as
hclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),
and some drivers can remove the checks of itself.

As Thomas suggested, timespec64_valid()\nonly check the timespec is valid, but not ensure that the time is\nin a valid range, so check it ahead using timespec64_valid_strict()\nin pc_clock_settime() and return -EINVAL if not valid.\n\nThere are some drivers that use tp-\u003etv_sec and tp-\u003etv_nsec directly to\nwrite registers without validity checks and assume that the higher layer\nhas checked it, which is dangerous and will benefit from this, such as\nhclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),\nand some drivers can remove the checks of itself."

Title
af_packet: avoid erroring out after sock_init_data() in packet_create()
Summary
In the Linux kernel, the following vulnerability has been resolved:
af_packet: avoid erroring out after sock_init_data() in packet_create()
After sock_init_data() the allocated sk object is attached to the provided
sock object. On error, packet_create() frees the sk object leaving the
dangling pointer in the sock object on return. Some other code may try
to use this pointer and cause use-after-free.
Severity
7.8 (High)
CWE
- CWE-416 - Use After Free

Title
nvme-pci: fix freeing of the HMB descriptor table
Summary
In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix freeing of the HMB descriptor table
The HMB descriptor table is sized to the maximum number of descriptors
that could be used for a given device, but __nvme_alloc_host_mem could
break out of the loop earlier on memory allocation failure and end up
using less descriptors than planned for, which leads to an incorrect
size passed to dma_free_coherent.
In practice this was not showing up because the number of descriptors
tends to be low and the dma coherent allocator always allocates and
frees at least a page.
Severity
5.5 (Medium)

Title
padata: avoid UAF for reorder_work
Summary
In the Linux kernel, the following vulnerability has been resolved:
padata: avoid UAF for reorder_work
Although the previous patch can avoid ps and ps UAF for _do_serial, it
can not avoid potential UAF issue for reorder_work. This issue can
happen just as below:
crypto_request crypto_request crypto_del_alg
padata_do_serial
...
padata_reorder
// processes all remaining
// requests then breaks
while (1) {
if (!padata)
break;
...
}
padata_do_serial
// new request added
list_add
// sees the new request
queue_work(reorder_work)
padata_reorder
queue_work_on(squeue->work)
...
<kworker context>
padata_serial_worker
// completes new request,
// no more outstanding
// requests
crypto_del_alg
// free pd
<kworker context>
invoke_padata_reorder
// UAF of pd
To avoid UAF for 'reorder_work', get 'pd' ref before put 'reorder_work'
into the 'serial_wq' and put 'pd' ref until the 'serial_wq' finish.

Title
ksmbd: fix Preauh_HashValue race condition
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix Preauh_HashValue race condition
If client send multiple session setup requests to ksmbd,
Preauh_HashValue race condition could happen.
There is no need to free sess->Preauh_HashValue at session setup phase.
It can be freed together with session at connection termination phase.
Severity
8.5 (High)
CWE
- CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Title
io_uring/futex: ensure io_futex_wait() cleans up properly on failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
io_uring/futex: ensure io_futex_wait() cleans up properly on failure
The io_futex_data is allocated upfront and assigned to the io_kiocb
async_data field, but the request isn't marked with REQ_F_ASYNC_DATA
at that point. Those two should always go together, as the flag tells
io_uring whether the field is valid or not.
Additionally, on failure cleanup, the futex handler frees the data but
does not clear ->async_data. Clear the data and the flag in the error
path as well.
Thanks to Trend Micro Zero Day Initiative and particularly ReDress for
reporting this.
