In the Linux kernel, the following vulnerability has been resolved: gfs2:
Fix slab-use-after-free in gfs2_qd_dealloc In gfs2_put_super(), whether
withdrawn or not, the quota should be cleaned up by gfs2_quota_cleanup().
Otherwise, struct gfs2_sbd will be freed before gfs2_qd_dealloc (rcu
callback) has run for all gfs2_quota_data objects, resulting in
use-after-free. Also, gfs2_destroy_threads() and gfs2_quota_cleanup() is
already called by gfs2_make_fs_ro(), so in gfs2_put_super(), after calling
gfs2_make_fs_ro(), there is no need to call them again.
