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