Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The issue is related to the `dml core mode programming` function in the AMD Display component of the Linux kernel. It involves an overlapping copy that may lead to unexpected behavior due to `memcpy` being used instead of `memmove`. The problem arises because `&mode lib->mp.Watermark` and `&locals->Watermark` share the same address. This could potentially allow an attacker to impact the availability of protected information. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

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.
