Use After Free vulnerability in Linux kernel traffic control index filter
(tcindex) allows Privilege Escalation. The imperfect hash area can be
updated while packets are traversing, which will cause a use-after-free
when ‘tcf_exts_exec()’ is called with the destroyed tcf_ext. A local
attacker user can use this vulnerability to elevate its privileges to root.
This issue affects Linux Kernel: from 4.14 before git commit
ee059170b1f7e94e55fa6cadee544e176a6e59c2.
