Google: sys-kernel/csql-kernel-6_12, sys-kernel/csql-kernel-6_6: security update to 19216.0.53

medium Tenable Cloud Security Plugin ID 468455

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: loop: Avoid updating block size under
exclusive owner Syzbot came up with a reproducer where a loop device block size is changed underneath a
mounted filesystem. This causes a mismatch between the block device block size and the block size stored
in the superblock causing confusion in various places such as fs/buffer.c. The particular issue triggered
by syzbot was a warning in __getblk_slow() due to requested buffer size not matching block device block
size. Fix the problem by getting exclusive hold of the loop device to change its block size. This fails if
somebody (such as filesystem) has already an exclusive ownership of the block device and thus prevents
modifying the loop device under some exclusive owner which doesn't expect it. (CVE-2025-38709)

Solution

Update the sys-kernel/csql-kernel-6_12 library and its related packages to version 19216.0.53 or later.
