Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
gfs2: Always check inode size of inline inodes<br />
<br />
Check if the inode size of stuffed (inline) inodes is within the allowed<br />
range when reading inodes from disk (gfs2_dinode_in()). This prevents<br />
us from on-disk corruption.<br />
<br />
The two checks in stuffed_readpage() and gfs2_unstuffer_page() that just<br />
truncate inline data to the maximum allowed size don&#39;t actually make<br />
sense, and they can be removed now as well.
