NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-modules-partner package and not the kernel-modules-partner package as distributed by Centos.
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In gfs2_put_super(), whether withdrawn or not, the quota should be cleaned up by gfs2_quota_cleanup().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.
