Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
fs/mount_setattr: always cleanup mount_kattr<br />
<br />
Make sure that finish_mount_kattr() is called after mount_kattr was<br />
succesfully built in both the success and failure case to prevent<br />
leaking any references we took when we built it. We returned early if<br />
path lookup failed thereby risking to leak an additional reference we<br />
took when building mount_kattr when an idmapped mount was requested.
