Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
libceph: remove debugfs files before client teardown<br />
<br />
ceph_destroy_client() tears down the monitor client before removing<br />
the per-client debugfs files. A concurrent read of the monmap debugfs<br />
file can enter monmap_show() after ceph_monc_stop() has freed<br />
monc->monmap, triggering a use-after-free.<br />
<br />
Remove the debugfs files before stopping the OSD and monitor clients.<br />
debugfs_remove() drains active handlers and prevents new accesses, so<br />
the debugfs callbacks can no longer race the rest of client teardown.
