CVE-2024-46714

CVE-2024-46714 in the Linux kernel is addressed by a fix in the DRM/AMD display path: the code now skips the wbscl_set_scaler_filter when the filter is null, preventing a potential NULL return from wbscl_get_filter_coeffs_16p from causing a null dereference. A null check was added to ensure filte...
