In the Linux kernel, the following vulnerability has been resolved: drm: Fix potential null-ptr-deref due to drmm_mode_config_init() drmm_mode_config_init() will call drm_mode_create_standard_properties() and won't check the ret value. When drm_mode_create_standard_properties() failed due to alloc, property will be a NULL pointer and may causes the null-ptr-deref. Fix the null-ptr-deref by adding the ret value check.
