VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description The issue is related to a NULL dereference of the timing generator in the drm/amd/display component of the Linux kernel. This can be exploited to cause a denial of service. The vulnerability occurs when the assigned timing generator is NULL, and its functions are accessed without proper checks. To prevent this, the kernel now checks whether the assigned timing generator is NULL before accessing its functions.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
