CVE-2025-40185 (GCVE-0-2025-40185)

Title
ice: ice_adapter: release xa entry on adapter allocation failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
ice: ice_adapter: release xa entry on adapter allocation failure
When ice_adapter_new() fails, the reserved XArray entry created by
xa_insert() is not released. This causes subsequent insertions at
the same index to return -EBUSY, potentially leading to
NULL pointer dereferences.
Reorder the operations as suggested by Przemek Kitszel:
1. Check if adapter already exists (xa_load)
2. Reserve the XArray slot (xa_reserve)
3. Allocate the adapter (ice_adapter_new)
4. Store the adapter (xa_store)
Severity
No CVSS data available.

Title
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
Summary
In the Linux kernel, the following vulnerability has been resolved:
tcp: Don't call reqsk_fastopen_remove() in tcp_conn_request().
syzbot reported the splat below in tcp_conn_request(). [0]
If a listener is close()d while a TFO socket is being processed in
tcp_conn_request(), inet_csk_reqsk_queue_add() does not set reqsk->sk
and calls inet_child_forget(), which calls tcp_disconnect() for the
TFO socket.
After the cited commit, tcp_disconnect() calls reqsk_fastopen_remove(),
where reqsk_put() is called due to !reqsk->sk.
Then, reqsk_fastopen_remove() in tcp_conn_request() decrements the
last req->rsk_refcnt and frees reqsk, and __reqsk_free() at the
drop_and_free label causes the refcount underflow for the listener
and double-free of the reqsk.
Let's remove reqsk_fastopen_remove() in tcp_conn_request().
Note that other callers make sure tp->fastopen_rsk is not NULL.
[0]:
refcount_t: underflow; use-after-free.

pwm: berlin: Fix wrong register in suspend/resume
Summary
In the Linux kernel, the following vulnerability has been resolved:
pwm: berlin: Fix wrong register in suspend/resume
The 'enable' register should be BERLIN_PWM_EN rather than
BERLIN_PWM_ENABLE, otherwise, the driver accesses wrong address, there
will be cpu exception then kernel panic during suspend/resume.

Title
cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()
Summary
In the Linux kernel, the following vulnerability has been resolved:
cpufreq: intel_pstate: Fix object lifecycle issue in update_qos_request()
The cpufreq_cpu_put() call in update_qos_request() takes place too early
because the latter subsequently calls freq_qos_update_request() that
indirectly accesses the policy object in question through the QoS request
object passed to it.
Fortunately, update_qos_request() is called under intel_pstate_driver_lock,
so this issue does not matter for changing the intel_pstate operation
mode, but it theoretically can cause a crash to occur on CPU device hot
removal (which currently can only happen in virt, but it is formally
supported nevertheless).
Address this issue by modifying update_qos_request() to drop the
reference to the policy later.
Severity
No CVSS data available.

Title
ext4: avoid potential buffer over-read in parse_apply_sb_mount_options()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ext4: avoid potential buffer over-read in parse_apply_sb_mount_options()
Unlike other strings in the ext4 superblock, we rely on tune2fs to
make sure s_mount_opts is NUL terminated. Harden
parse_apply_sb_mount_options() by treating s_mount_opts as a potential
__nonstring.
Severity
No CVSS data available.

Title
Squashfs: reject negative file sizes in squashfs_read_inode()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: reject negative file sizes in squashfs_read_inode()
Syskaller reports a "WARNING in ovl_copy_up_file" in overlayfs.
This warning is ultimately caused because the underlying Squashfs file
system returns a file with a negative file size.
This commit checks for a negative file size and returns EINVAL.
[phillip@squashfs.org.uk: only need to check 64 bit quantity]

Title
btrfs: avoid potential out-of-bounds in btrfs_encode_fh()
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: avoid potential out-of-bounds in btrfs_encode_fh()
The function btrfs_encode_fh() does not properly account for the three
cases it handles.
Before writing to the file handle (fh), the function only returns to the
user BTRFS_FID_SIZE_NON_CONNECTABLE (5 dwords, 20 bytes) or
BTRFS_FID_SIZE_CONNECTABLE (8 dwords, 32 bytes).
However, when a parent exists and the root ID of the parent and the
inode are different, the function writes BTRFS_FID_SIZE_CONNECTABLE_ROOT
(10 dwords, 40 bytes).
If *max_len is not large enough, this write goes out of bounds because
BTRFS_FID_SIZE_CONNECTABLE_ROOT is greater than
BTRFS_FID_SIZE_CONNECTABLE originally returned.
This results in an 8-byte out-of-bounds write at
fid->parent_root_objectid = parent_root_id.
A previous attempt to fix this issue was made but was lost.
https://lore.kernel.org/all/4CADAEEC020000780001B32C@vpn.id2.novell.com/
Although this issue does not seem to be easily triggerable, it is a
potential memory corruption bug that should be fixed. This patch
resolves the issue by ensuring the function returns the appropriate size
for all three cases and validates that *max_len is large enough before
writing any data.

netfilter: nft_objref: validate objref and objrefmap expressions
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_objref: validate objref and objrefmap expressions
Referencing a synproxy stateful object from OUTPUT hook causes kernel
crash due to infinite recursive calls:
BUG: TASK stack guard page was hit at 000000008bda5b8c (stack is 000000003ab1c4a5..00000000494d8b12)

[...]
Implement objref and objrefmap expression validate functions.
Currently, only NFT_OBJECT_SYNPROXY object type requires validation.
This will also handle a jump to a chain using a synproxy object from the
OUTPUT hook.
Now when trying to reference a synproxy object in the OUTPUT hook, nft
will produce the following error:
synproxy_crash.nft: Error: Could not process rule: Operation not supported
synproxy name mysynproxy

media: v4l2-subdev: Fix alloc failure check in v4l2_subdev_call_state_try()
Summary
In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-subdev: Fix alloc failure check in v4l2_subdev_call_state_try()
v4l2_subdev_call_state_try() macro allocates a subdev state with
__v4l2_subdev_state_alloc(), but does not check the returned value. If
__v4l2_subdev_state_alloc fails, it returns an ERR_PTR, and that would
cause v4l2_subdev_call_state_try() to crash.
Add proper error handling to v4l2_subdev_call_state_try().
