LinuxVULNRICHMENT:CVE-2024-43894CVE-2024-43894 drm/client: fix null pointer dereference in drm_client_modeset_probe
In the Linux kernel, the following vulnerability has been resolved:
drm/client: fix null pointer dereference in drm_client_modeset_probe
In drm_client_modeset_probe(), the return value of drm_mode_duplicate() is
assigned to modeset->mode, which will lead to a possible NULL pointer
dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.
