Security readout for executives and security teams
CVE-2011-4077 is a Linux kernel XFS bug in old 2.6-era kernels. A local user who can get a crafted XFS image processed could corrupt kernel memory, causing a crash and possibly code execution. It is not listed in KEV, and the provided sources do not show active exploitation. Exposure is most likely on legacy Linux 2.6 systems using or mounting XFS, especially where untrusted local users or processes can introduce filesystem images. The provided affected-product data is incomplete and lists no specific vendor package versions. Treat this as a legacy infrastructure hygiene issue unless affected kernels remain in production. It warrants prompt remediation on systems that process untrusted storage images because kernel crashes can affect availability and possible code execution raises privilege-risk concerns. Mitigation focus: Identify systems running Linux kernel 2.6 with XFS support.; Prioritize vendor kernel updates that include the XFS readlink memory-corruption fix.; Restrict untrusted users from mounting or supplying filesystem images..
