CVE-2022-49739 Information

Description

In the Linux kernel the following vulnerability has been resolved:

gfs2: Always check inode size of inline inodes

Check if the inode size of stuffed (inline) inodes is within the allowed range when reading inodes from disk (gfs2_dinode_in()). This prevents us from on-disk corruption.

The two checks in stuffed_readpage() and gfs2_unstuffer_page() that just truncate inline data to the maximum allowed size don’t actually make sense and they can be removed now as well.
