CVE-2023-1829 – Use-after-free in tcindex (traffic control index filter) in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-1829
12 Apr 2023 — A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.
