Loading vulnerability…
CVE-2022-0995 is an out-of-bounds memory write in the Linux kernel watch_queue event-notification subsystem. A local unprivileged user can trigger a write beyond an intended memory-buffer boundary, overwriting portions of kernel state. Corruption of kernel memory may be leveraged for local privilege escalation or may destabilize the kernel.

This repository contains a single Metasploit module implementing a local privilege escalation exploit for CVE-2022-0995, a heap out-of-bounds write vulnerability in the Linux kernel's watch_queue event notification system. The exploit targets Ubuntu Linux 5.13.0-37-generic (x86_64) and requires a local session on the target system. The module checks for the correct kernel version and architecture, uploads and compiles (or drops a precompiled) exploit binary to a writable directory (default: /tmp), uploads a user-supplied payload (such as a shell or meterpreter), and executes the exploit to run the payload as root. The exploit is operational but may require multiple attempts due to heap spray reliability. The module is part of the Metasploit framework and is structured to clean up dropped files and directories after execution. No network endpoints are involved; the attack vector is purely local.
This repository contains a working exploit for CVE-2022-0995, a local privilege escalation vulnerability in the Linux kernel (tested on version 5.13.18). The exploit is implemented in C (exploit.c) and is accompanied by a README.md with build instructions and references. The exploit works by abusing the watch_queue subsystem and message queue spraying to achieve a use-after-free condition, leak kernel heap and base addresses, and ultimately gain code execution in kernel context. The payload creates a setuid-root shell at /tmp/shell, which is then executed to provide the attacker with a root shell. The exploit is operational and requires local access to the target system. The main fingerprintable endpoints are the files /tmp/shell, /tmp/x, and /tmp/trigger, which are created and used during exploitation. The repository is structured simply, with the main exploit logic in exploit.c and documentation in README.md.
This repository contains a local privilege escalation exploit for CVE-2022-0995, a heap out-of-bounds write vulnerability in the Linux kernel's watch_queue subsystem. The exploit is implemented in C and consists of three main files: 'exploit.c' (main exploit logic), 'util.c', and 'util.h' (helper functions and structures). The Makefile is provided for building a statically linked binary. The exploit targets Ubuntu 21.10 with kernel 5.13.0-37 and works by spraying kernel heap objects, leaking the KASLR base, and constructing a ROP chain to escalate privileges. Upon successful exploitation, a root shell is spawned. The exploit requires local access to the vulnerable system and is not 100% reliable, as noted in the README. No network endpoints are involved; the attack vector is purely local. The code demonstrates advanced kernel exploitation techniques, including heap spraying, KASLR bypass, and ROP chain construction.
