CVE-2022-49174 ext4: fix ext4_mb_mark_bb() with flex_bg with fast_commit

In the Linux kernel, the following vulnerability has been resolved: ext4: fix ext4mbmarkbb with flexbg with fastcommit In case of flexbg feature which is by default enabled, extents for any given inode might span across blocks from two different block group. ext4mbmarkbb only reads the bufferhead...

CVE-2022-49174

CVE-2022-49174 affects the Linux kernel ext4 filesystem, specifically the ext4_mb_mark_bb() logic when flex_bg (default enabled) and fast_commit are used. The issue occurs when an inode’s extents span block groups and ext4_mb_mark_bb() reads the starting block group’s bitmap only once; it does no...
