**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 5.12.11 **Description** The issue is related to the incorrect computation of access permissions for a shadow page in the Linux kernel, leading to a missing guest protection page fault. This could potentially allow an attacker to cause a denial of service. The estimated number of potentially affected devices and details about real-world incidents are not provided. **Recommendations** For versions prior to 5.12.11, update to version 5.12.11 or later to resolve the issue. As a temporary workaround, consider restricting access to critical resources to minimize the risk of exploitation.
