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.

Affected configurations

• linux linux kernel (< 4.19.280) • linux linux kernel (>= 4.20 < 5.4.240) • linux linux kernel (>= 5.5 < 5.10.177) • linux linux kernel (>= 5.11 < 5.15.93) • linux linux kernel (>= 5.16 < 6.1.11)
