Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
A null pointer dereference issue has been resolved in the Linux kernel. The problem occurred because the
set output gamma function pointer was being dereferenced without a null check in the dcn401 set output transfer func function. This could have led to a null pointer dereference if set output gamma was null. The issue has been fixed by adding a null check for set output gamma before it is dereferenced.Recommendations:
To resolve this issue, update the Linux kernel to a version that includes the fix for the null pointer dereference in the
dcn401 set output transfer func function. As a temporary workaround, consider disabling the dcn401 set output transfer func function until a patch is available. However, since the exact affected versions are not specified, it is crucial to ensure that the update includes the necessary patch for the drm/amd/display component. At the moment, there is no information about a newer version that contains a fix for this vulnerability, so users should monitor for updates from the Linux kernel maintainers.Exploit
