The (1) udp_recvmsg and (2) udpv6_recvmsg functions in the Linux kernel before 4.0.6 do not properly consider yielding a processor, which allows remote attackers to cause a denial of service (system hang) via incorrect checksums within a UDP packet flood.

Security readout for executives and security teams

CVE-2015-5364 is a Linux kernel availability issue. A remote actor could send malformed UDP traffic and cause affected systems to hang. The business risk is service outage, not data theft, based on the supplied sources. Exposure is most likely on Linux systems running affected pre-4.0.6 kernels or vendor-maintained kernels addressed by Ubuntu, SUSE, Red Hat, Debian, or Oracle advisories. Internet-facing UDP workloads deserve priority review. Treat as a targeted availability risk. Prioritize patch verification on exposed Linux infrastructure and critical services where a system hang would disrupt operations. Mitigation focus: Apply relevant vendor kernel security updates for the deployed distribution.; Upgrade to a kernel containing the upstream 4.0.6 fix or vendor backport.; Prioritize internet-facing systems that accept UDP traffic..
