MEDIUMLinux Kernel < 3.1 - Denial of Service via Performance Events Subsystem
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2011-2918. PoCs published by Vince Weaver.
AI-analyzed exploit summary This exploit triggers an integer overflow in the Linux kernel's performance event subsystem (PERF_COUNT_SW_CPU_CLOCK) by creating a high-frequency event counter and inducing overflows during matrix multiplication. It demonstrates a DoS condition by crashing Linux kernel 3.0.0.
Description
The Performance Events subsystem in the Linux kernel before 3.1 does not properly handle event overflows associated with PERF_COUNT_SW_CPU_CLOCK events, which allows local users to cause a denial of service (system hang) via a crafted application.
