Description
An issue was discovered in fs/gfs2/rgrp.c in the Linux kernel before 4.8. A
use-after-free is caused by the functions gfs2_clear_rgrpd and
read_rindex_entry.
Ubuntu-Description
It was discovered that a race condition existed in the GFS2 file system in
the Linux kernel. A local attacker could possibly use this to cause a
denial of service (system crash).
