crypto/ghash-generic.c in the Linux kernel before 3.1 allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact by triggering a failed or missing ghash_setkey function call, followed by a (1) ghash_update function call or (2) ghash_final function call, as demonstrated by a write operation on an AF_ALG socket.

Security readout for executives and security teams

CVE-2011-4081 is a Linux kernel flaw that can let a local user crash the system through the kernel crypto GHASH implementation. The public record describes denial of service and only possible unspecified other impact. It is fixed before or in Linux kernel 3.1-era updates. Exposure is most relevant to systems running Linux kernels before 3.1, or vendor kernels without the referenced backport. The sources support local-user impact, not remote network exploitation. Multi-user systems and hosts running untrusted local workloads deserve closer attention. Treat this as a moderate operational resilience issue. It is local, not known exploited from the provided sources, but can crash affected systems. Prioritize legacy Linux hosts, shared environments, and systems where untrusted users or workloads can execute locally. Mitigation focus: Upgrade to Linux kernel 3.1 or a vendor kernel containing the referenced fix.; Check distribution advisories for backported kernel packages and support status.; Prioritize patching multi-user systems and hosts running untrusted local workloads..
