Google: sys-kernel/csql-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.104.3

high Tenable Self-Hosted Container Security Plugin ID 472939

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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/[email protected]/ 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. (CVE-2025-40205)
