Title source: llm
STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2006-7051. PoCs published by fingerout.

AI-analyzed exploit summary This exploit code is a proof-of-concept for a local denial-of-service (DoS) attack targeting the Linux kernel's OOM (Out of Memory) killer. It creates multiple threads that consume memory, each with a low OOM score to avoid being killed, leading to system instability.

Description

The sys_timer_create function in posix-timers.c for Linux kernel 2.6.x allows local users to cause a denial of service (memory consumption) and possibly bypass memory limits or cause other processes to be killed by creating a large number of posix timers, which are allocated in kernel memory but are not treated as part of the process' memory.
