CVE-2013-1767: Use-after-free vulnerability in the shmem_remount_fs function in mm/shmem.c in the Linux kernel before 3.7....

Security readout for executives and security teams

This is an old Linux kernel memory-safety flaw in tmpfs remount handling. A local user could potentially crash the system or gain higher privileges. Business risk is highest on legacy Linux hosts, shared servers, or environments where untrusted users can run local code. Exposure is likely limited to Linux systems running vulnerable kernel versions or downstream vendor kernels covered by the cited 2013 advisories. The provided bundle does not enumerate exact affected distribution package versions, so validation must use each vendor advisory and the active running kernel. Treat as high priority for legacy or shared Linux environments because successful exploitation could produce root-level impact or outages. For modern, supported Linux fleets, urgency depends on whether any affected 2013-era kernels remain active. Mitigation focus: Apply the relevant vendor kernel security update for affected Linux distributions.; For upstream kernels, ensure the fix included before Linux 3.7.10 is present.; Reboot systems after kernel update so the fixed kernel is active..
