LIN1022-6637 : Security Advisory - linux - CVE-2024-26601

Created: Feb 25, 2024    Updated: Feb 18, 2025
Resolved Date: Mar 22, 2024
Found In Version: 10.22.33.1
Fix Version: 10.22.33.16
Severity: Standard
Applicable for: Wind River Linux LTS 22
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

ext4: regenerate buddy after block freeing failed if under fc replay

This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant
mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). Based on
code in mb_free_blocks(), fast commit replay can end up marking as free
blocks that are already marked as such. This causes corruption of the
buddy bitmap so we need to regenerate it in that case.
