21 May 2024 — 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vulnerability has been resolved: gfs2: Fix slab-use-after-free in gfs2_qd_dealloc In gfs2_put_super(), whether withdrawn or not, the quota should be cleaned up by gfs2_quota_cleanup().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_ma... • https://git.kernel.org/stable/c/7ad4e0a4f61c57c3ca291ee010a9d677d0199fba • CWE-416: Use After Free •

It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor.
