Description

A flaw was found in the Linux kernel's drm/amd/display component. This flaw occurs because the dcn401_init_hw() function does not properly validate a callback pointer (update_bw_bounding_box) before use. This can lead to a NULL pointer dereference, potentially causing a system crash or denial of service.

Mitigation

No mitigation is specified in collected source.
