CVE-2022-2639

This repository contains a functional exploit for CVE-2022-2639, a Linux kernel openvswitch local privilege escalation vulnerability. The exploit leverages the pipe-primitive technique to bypass modern kernel protections like KASLR, SMAP, and SMEP, achieving root privileges by overwriting /usr/bin/mount with a SUID shell.

This is a functional local privilege escalation (LPE) exploit for CVE-2022-2639, targeting a heap out-of-bounds write vulnerability in the Linux kernel's openvswitch module. It leverages the pipe-primitive technique to bypass modern mitigations like KASLR, SMAP, and SMEP, achieving root by overwriting /usr/bin/mount with a SUID shell.

This repository contains a shell script to detect and mitigate CVE-2022-2639 by checking if the Open vSwitch kernel module is blacklisted and optionally applying the mitigation. It does not exploit the vulnerability but provides a remediation script.

This repository contains a functional exploit for CVE-2022-2639, a Linux kernel openvswitch local privilege escalation vulnerability. The exploit leverages a pipe primitive to bypass KASLR and other protections, demonstrating a reliable LPE attack.
