**Name of the Vulnerable Software and Affected Versions** Linux kernel KVM hypervisor versions prior to 4.18 **Description** A flaw was found in the way Linux kernel KVM hypervisor emulated certain instructions. It did not check the current privilege level while emulating unprivileged instructions, which could allow an unprivileged guest user or process to potentially escalate privileges inside the guest. **Recommendations** For versions prior to 4.18, update to version 4.18 or later to resolve the issue. As a temporary workaround, consider restricting access to unprivileged instructions until a patch is available.
