Overview
About vulnerability
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.
