The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced.

Security readout for executives and security teams

This is an older Linux kernel denial-of-service flaw. A local user could trigger a kernel over-read and crash the system, causing downtime. The sources do not show remote compromise, privilege escalation, or confirmed active exploitation. Risk is mainly to legacy Linux or Android-derived systems that still run affected, unpatched kernels. Exposure is most plausible on legacy Linux kernels through 3.14.3 or downstream vendor kernels covered by Ubuntu, Debian, Oracle, or Android advisories that were not updated. Modern maintained distributions are less likely exposed, but embedded, appliance, and long-lived Android/Linux builds need verification. Schedule remediation for legacy or shared Linux systems, especially where downtime affects operations. This is not supported as an internet-facing remote compromise issue by the provided sources, but unpatched local crash bugs still matter on shared hosts and appliances. Mitigation focus: Apply vendor kernel updates from the relevant Linux or Android advisory.; Confirm fixes include upstream Linux commit 05ab8f2647e4221cbdb3856dd7d32bd5407316b3.; Reboot systems into the updated kernel after patching..
