Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.50
Description
A null pointer dereference vulnerability has been resolved in the Linux kernel. The issue was related to the
drm/amdgpu/pm module, where a null pointer (hwmgr->backend) was being passed to the smu7 update edc leakage table function. This vulnerability has been fixed by optimizing the code to avoid passing null pointers.Recommendations
To resolve this issue, update the Linux kernel to version 6.6.50 or later. As a temporary workaround, consider disabling the
smu7 update edc leakage table function until a patch is available. Restrict access to the drm/amdgpu/pm module to minimize the risk of exploitation. Avoid using the hwmgr->backend pointer in the affected code until the issue is resolved.Exploit
