## Overview

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

netconsole: take target_cleanup_list_lock in drop_netconsole_target()

drop_netconsole_target() unlinks the target while only holding
target_list_lock. However, when the underlying interface has been
unregistered, netconsole_netdev_event() moves the target from
target_list to target_cleanup_list, and netconsole_process_cleanups_core()
walks that list under target_cleanup_list_lock only.

If a user removes the configfs target at the same time the cleanup
worker is iterating target_cleanup_list, list_del() can corrupt the list
because the two paths take disjoint locks while operating on the same
list node.

Acquire target_cleanup_list_lock around the list_del() so the unlink is
serialised against netconsole_process_cleanups_core() regardless of
which list the target currently belongs to. The state transition that
downgrades STATE_DEACTIVATED to STATE_DISABLED is left intact and is
performed under the same combined locking, preserving the existing
ordering with resume_target().
