CVE-2022-0171 is a medium-severity vulnerability in the Linux kernel's KVM SEV API, affecting various Debian and Red Hat Linux distributions. It allows a non-root user-level application on the host to crash the host kernel by creating a confidential guest VM instance on AMD CPUs with Secure Encrypted Virtualization (SEV). The attack requires local access and has low complexity, leading to a denial of service. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
