FreeBSD 9.3 before p33, 10.1 before p26, and 10.2 before p9 allow remote attackers to cause a denial of service (kernel crash) via vectors related to creating a TCP connection with the TCP_MD5SIG and TCP_NOOPT socket options.

Security readout for executives and security teams

This flaw can let a remote attacker crash vulnerable FreeBSD systems, causing a denial of service. It affects older FreeBSD 9.3, 10.1, and 10.2 patch levels listed in the CVE. The sources do not show code execution or data theft, but a kernel crash can still disrupt exposed services. Exposure is most likely on legacy FreeBSD hosts running the affected patch levels and reachable by untrusted network traffic. The source bundle does not identify affected downstream products, appliances, or configurations beyond FreeBSD itself. Prioritize remediation for internet-facing or business-critical FreeBSD systems. The issue is availability-focused, but a remote kernel crash can create service outages and operational disruption. Mitigation focus: Apply FreeBSD-SA-16:05 updates for affected FreeBSD releases.; Upgrade legacy FreeBSD systems to supported releases where feasible.; Restrict untrusted network access to exposed affected hosts..
