CVEID:CVE-2023-4155
**DESCRIPTION:**Linux Kernel is vulnerable to a denial of service, caused by a race condition in KVM AMD Secure Encrypted Virtualization (SEV). By sending a specially crafted request using the VMGEXIT handler recursively, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/266090 for the current score.
