In the Linux kernel, the following vulnerability has been resolved:

libceph: remove debugfs files before client teardown

ceph_destroy_client() tears down the monitor client before removing

the per-client debugfs files. A concurrent read of the monmap debugfs

file can enter monmap_show() after ceph_monc_stop() has freed

monc->monmap, triggering a use-after-free.

Remove the debugfs files before stopping the OSD and monitor clients.

debugfs_remove() drains active handlers and prevents new accesses, so

the debugfs callbacks can no longer race the rest of client teardown. (NVD)
