Vulnerability in Linux Kernel Affecting DRM/MSM Components

CVE-2025-68314

What is CVE-2025-68314?

A vulnerability exists in the Linux kernel's DRM/MSM components where the last_fence may not be properly updated. This oversight can lead to resource management issues, specifically in vm_bind contexts. When the context closes, if last_fence is not waited on, it can result in resource faults due to premature resource deallocation. The issue underscores the importance of ensuring that last_fence is updated accurately in all relevant paths, primarily when managing virtual memory bindings. A patch has been deployed to address this issue, enhancing the stability and reliability of the Linux kernel.
