Exploitation Summary

EIP tracks 1 public exploit for CVE-2023-1829. PoCs published by lanleft.

AI-analyzed exploit summary This repository contains a proof-of-concept exploit for CVE-2023-1829, targeting a Linux kernel vulnerability. The exploit leverages netlink operations to achieve local privilege escalation (LPE) by manipulating traffic control (tc) filters and actions.

Description

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.
