Security readout for executives and security teams

CVE-2016-8630 is a Linux kernel KVM flaw that could let a local user crash the host operating system. For businesses, the concern is availability of virtualization hosts, not data theft or remote takeover based on the supplied sources. Exposure is mainly Linux systems running kernel versions before 4.8.7 with KVM enabled. Virtualization hosts or systems allowing untrusted local users or guest workloads deserve priority review. The supplied affected metadata is incomplete beyond the Linux kernel description. Prioritize patching shared or production virtualization hosts where a crash would disrupt services. This is not evidenced as actively exploited in the supplied sources, but host-level denial of service can still create material operational impact. Mitigation focus: Upgrade affected Linux kernels to 4.8.7 or a vendor-fixed kernel.; Apply relevant Red Hat advisories RHSA-2017:0386 or RHSA-2017:0387 where applicable.; Limit untrusted local access to KVM-enabled hosts until patched..
