CVE-2023-52815 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/amdgpu/vkms: fix a possible null pointer dereference

In amdgpu_vkms_conn_get_modes() the return value of drm_cvt_mode() is assigned to mode which will lead to a NULL pointer dereference on failure of drm_cvt_mode(). Add a check to avoid null pointer dereference.
