Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: guard against NULL restore_mqd in CRIU queue restore Both create_queue_cpsch() and create_queue_nocpsch() unconditionally call mqd_mgr->restore_mqd() when a CRIU restore is in progress (qd != NULL), with no NULL guard. On any system where restore_mqd is not implemented for the given queue type, a user holding CAP_CHECKPOINT_RESTORE can trigger a kernel NULL pointer dereference and panic the machine by issuing KFD_IOC_CRIU_OP_RESTORE with a crafted queue restore object. Note that checkpoint_mqd is likewise unimplemented on GFX12, so no legitimate CRIU image can reach this path — only a hand-crafted restore payload. Add a NULL guard for restore_mqd immediately after mqd_mgr is resolved, unwinding via the existing error labels and returning -EOPNOTSUPP if the callback is not implemented. This mirrors the existing checkpoint_mqd guard in checkpoint_mqd().
