CVE-2024-53133 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Handle dml allocation failure to avoid crash [Why] In the case where a dml allocation fails for any reason, the current state's dml contexts would no longer be valid.
