CVE-2022-49348 – ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that we are in the middle of replay the fast commit journal. This was actually a mistake, since the sbi->s_mount_info is initialized from es->s_state. Arguably s_mount_state is misleadingly named, but the name is historical --- s_mount_state and s_state dates back to ext2.

CVE-2022-49343 – ext4: avoid cycles in directory h-tree
https://notcve.org/view.php?id=CVE-2022-49343
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: ext4: avoid cycles in directory h-tree A maliciously corrupted filesystem can contain cycles in the h-tree stored inside a directory. That can easily lead to the kernel corrupting tree nodes that were already verified under its hands while doing a node split and consequently accessing unallocated memory. Fix the problem by verifying traversed block numbers are unique. • https://git.kernel.org/stable/c/24b8206fec1db21d7e82f21f0b2ff5e5672cf5b3 •
