CVE-2022-39188

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.19

Description The issue is related to a race condition in the Linux kernel, specifically in the unmap mapping range function, which can lead to a situation where a device driver frees a page while it still has stale TLB entries. This occurs in situations with VM PFNMAP VMAs, potentially allowing an attacker to cause a denial of service.

Recommendations For Linux kernel versions prior to 5.19, update to version 5.19 or later to resolve the issue. As a temporary workaround, consider restricting access to the unmap mapping range function to minimize the risk of exploitation.
