CVE-2014-4699: The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value...

Security readout for executives and security teams

CVE-2014-4699 is an old Linux kernel flaw on Intel processors. A local user or compromised local process could use it to gain higher privileges or crash the system. It is not a remote entry point, but it matters on shared servers, hosting environments, and systems where untrusted users or workloads can run code. Exposure is likely limited to Intel-based Linux systems running vulnerable pre-3.15.4 kernels or affected vendor kernel builds. Shared Linux hosts, developer systems, and multi-tenant workloads carry more risk than single-purpose appliances with no local code execution path. Treat this as high priority for legacy or shared Linux environments. It is not internet-remote by itself, but it can turn a foothold into root access or cause outages on vulnerable Intel systems. Mitigation focus: Apply vendor kernel updates from Ubuntu, Oracle, or the relevant Linux distributor.; Move to a kernel version containing the upstream fix, such as 3.15.4 or vendor backports.; Reboot systems after kernel updates so the fixed kernel is active..
