The futex_wait_requeue_pi function in kernel/futex.c in the Linux kernel before 3.5.1 does not ensure that calls have two different futex addresses, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted FUTEX_WAIT_REQUEUE_PI command.

Security readout for executives and security teams

This is an old Linux kernel flaw that could let a local user crash the system by abusing a futex operation. It is mainly a reliability and availability risk, not a confirmed remote compromise issue. Systems are most exposed where untrusted users or workloads can run local code. Exposure appears limited to Linux kernels before 3.5.1 or vendor kernels missing the referenced futex fix. The attacker must be a local user or able to run local code. No affected vendor product list is provided in the source bundle. Treat as a targeted availability risk for legacy Linux systems. It is not evidence of a current remote breach risk, but unpatched shared or business-critical hosts should be remediated because a local crash can disrupt services. Mitigation focus: Upgrade to Linux kernel 3.5.1 or a vendor-supported kernel containing the futex fix.; Check distribution advisories for backported fixes on supported enterprise kernels.; Reduce untrusted local user or workload access on unpatched systems..
