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.
Found null-ptr-deref while testing insert module bochs:
