Descriptions
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.
A use-after-free vulnerability was found in the traffic control index filter (tcindex) in the Linux kernel. The imperfect hash area can be updated while packets are traversing. This issue could allow a local attacker to cause a use-after-free problem, leading to privilege escalation.
