CVE-2023-1281: UAF in Linux kernel's tcindex (traffic control index filter) implementation

First published: Wed Mar 22 2023(Updated: )

A 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 href="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ee059170b1f7e94e55fa6cadee544e176a6e59c2">https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ee059170b1f7e94e55fa6cadee544e176a6e59c2</a>
