CVE-2016-2547
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b5a663aa426f4884c71cd8580adae73f33570f0d
"A slave timer instance might be still accessible in a racy way while
operating the master instance as it lacks of locking. Since the master
operation is mostly protected with timer->lock, we should cope with it
while changing the slave instance, too."


CVE-2016-2548
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b5a663aa426f4884c71cd8580adae73f33570f0d
"some linked lists (active_list and ack_list) of slave instances
aren't unlinked immediately at stopping or closing, and this may lead
to unexpected accesses."
