CVE-2024-26772

CVE-2024-26772: In the Linux kernel, the fix prevents allocating blocks from a corrupted ext4 group. The patch moves the block bitmap integrity check under the group lock in ext4_mb_find_by_goal(), ensuring blocks are not allocated from a group with a corrupted bitmap. This mitigates a local-priv...
