What the advisory describes

In the Linux kernel, the following vulnerability has been resolved: NFSD: Handle layout stid in nfsd4_drop_revoked_stid() nfsd4_drop_revoked_stid() has no SC_TYPE_LAYOUT case, so when a client sends FREE_STATEID for an admin-revoked layout stid, the default branch releases cl_lock and returns without unhashing or releasing the stid. The stid remains in the IDR and on the per-client list until the client is destroyed. Remove the layout stid from the per-client list and call nfs4_put_stid() to drop the creation reference. When the refcount reaches zero, nfsd4_free_layout_stateid() handles the remaining cleanup: cancelling the fence worker, removing from the per-file list, and freeing the slab object.

Source: EUVD (ENISA), in the words of the advisory.
