      "title": "drm/amdkfd: guard against NULL restore_mqd in CRIU queue restore",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amdkfd: guard against NULL restore_mqd in CRIU queue restore\n\nBoth create_queue_cpsch() and create_queue_nocpsch() unconditionally\ncall mqd_mgr->restore_mqd() when a CRIU restore is in progress\n(qd != NULL), with no NULL guard. On any system where restore_mqd is\nnot implemented for the given queue type, a user holding\nCAP_CHECKPOINT_RESTORE can trigger a kernel NULL pointer dereference\nand panic the machine by issuing KFD_IOC_CRIU_OP_RESTORE with a\ncrafted queue restore object. Note that checkpoint_mqd is likewise\nunimplemented on GFX12, so no legitimate CRIU image can reach this\npath — only a hand-crafted restore payload.\n\nAdd a NULL guard for restore_mqd immediately after mqd_mgr is\nresolved, unwinding via the existing error labels and returning\n-EOPNOTSUPP if the callback is not implemented. This mirrors the\nexisting checkpoint_mqd guard in checkpoint_mqd().",
