Security readout for executives and security teams

CVE-2016-4794 is a Linux kernel memory safety flaw. A local user or process could trigger a kernel crash and may have other unspecified impact. It matters most on older or unpatched Linux systems that allow untrusted local code execution. Exposure is most likely on Linux systems running kernels through 4.6 or distribution kernels that had not yet incorporated vendor fixes. Systems with untrusted local shell, container, application, or mobile code execution deserve priority review. Treat as a maintenance-priority kernel issue, higher on shared hosts or systems running untrusted code. It is not supported as remotely exploitable or actively exploited in the provided sources, but kernel crashes can still disrupt critical services. Mitigation focus: Apply supported vendor kernel security updates from Ubuntu, Red Hat, Android, or your distribution.; Retire unsupported kernels at or before Linux 4.6 where vendor fixes are unavailable.; Restrict untrusted local code execution on shared, container, and multi-user systems..
