In the Lustre file system before 2.12.3, mdt_object_remote in the mdt module has a NULL pointer dereference and panic due to the lack of validation for specific fields of packets sent by a client.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
