CVE-2013-6763: The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the s...

Security readout for executives and security teams

This is an old Linux kernel flaw in the UIO memory-mapping path. A local user could potentially crash the system through memory corruption, and the CVE record says privilege gain may be possible. It is most relevant to legacy or unpatched Linux systems, not remotely exposed services by itself. Exposure is likely limited to systems running Linux kernels before 3.12, or vendor kernels without the backported fix. Local access is required. Highest concern is older servers, appliances, embedded systems, or long-lived images where kernel updates lag. Treat as a high-priority legacy Linux hygiene issue where affected kernels remain in use. It is not evidenced as internet-exploitable or actively exploited, but possible local privilege gain in the kernel warrants prompt remediation on shared or sensitive systems. Mitigation focus: Upgrade to a kernel containing the upstream fix or vendor backport.; Apply the relevant Ubuntu USN kernel updates where applicable.; Reboot systems so the patched kernel is active..
