Linux kernel <2.6.25 - Memory Corruption

Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 2 public exploits for CVE-2008-0009.

AI-analyzed exploit summary This is a functional local privilege escalation exploit for CVE-2008-0009, targeting a vulnerability in the Linux kernel's vmsplice system call (2.6.23-2.6.24). It manipulates kernel memory to escalate privileges to root by overwriting process credentials.

Description

The vmsplice_to_user function in fs/splice.c in the Linux kernel 2.6.22 through 2.6.24 does not validate a certain userspace pointer before dereference, which might allow local users to access arbitrary kernel memory locations.
