Google: sys-kernel/lakitu-kernel-6_1: security update to 18244.85.5

high Tenable Self-Hosted Container Security Plugin ID 451770

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: ext4: fix double-free of blocks due to
wrong extents moved_len In ext4_move_extents(), moved_len is only updated when all moves are successfully
executed, and only discards orig_inode and donor_inode preallocations when moved_len is not zero. When the
loop fails to exit after successfully moving some extents, moved_len is not updated and remains at 0, so
it does not discard the preallocations. If the moved extents overlap with the preallocated extents, the
overlapped extents are freed twice in ext4_mb_release_inode_pa() and ext4_process_freed_data() (as
described in commit 94d7c16cbbbd ("ext4: Fix double-free of blocks with EXT4_IOC_MOVE_EXT")), and bb_free
is incremented twice. Hence when trim is executed, a zero-division bug is triggered in
mb_update_avg_fragment_size() because bb_free is not zero and bb_fragments is zero. Therefore, update
move_len after each extent move to avoid the issue. (CVE-2024-26704)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18244.85.5 or later.
