Title source: llm
STIX 2.1

CVE-2010-3081 has been observed exploited in the wild (reported by VulnCheck KEV, InTheWild.io). EIP tracks 1 public exploit from researchers including Ac1dB1tCh3z.

AI-analyzed exploit summary This exploit targets a Linux kernel vulnerability (CVE-2010-3081) in the MCAST_MSFILTER compat mode, allowing local privilege escalation. It includes shellcode and techniques to bypass security mechanisms like SELinux and OpenVZ.

Description

The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit compatibility layer, which allows local users to gain privileges by leveraging the ability of the compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length value, related to a "stack pointer underflow" issue, as exploited in the wild in September 2010.
