  "description": "In the Linux kernel, the following vulnerability has been resolved:  accel/amdxdna: reject user command submission without a command BO  amdxdna_drm_submit_execbuf() passes the user-supplied command BO handle straight into amdxdna_cmd_submit() with drv_cmd == NULL. When the handle is AMDXDNA_INVALID_BO_HANDLE (0), the block that fetches job-\u003Ecmd_bo is skipped, leaving it NULL, and no check rejects it on the user path (the !job-\u003Ecmd_bo guard lives inside the != INVALID branch).  The job is then armed and pushed to the DRM scheduler. aie2_sched_job_run() takes the drv_cmd == NULL path and calls amdxdna_cmd_set_state(job-\u003Ecmd_bo) -\u003E amdxdna_gem_vmap(NULL) -\u003E to_gobj(NULL)-\u003Edev, a NULL pointer dereference in the drm_sched worker. A process with access to the accel node on a system with a probed AMD NPU can trigger a kernel oops with a single AMDXDNA_EXEC_CMD ioctl (cmd_handles = 0).  Only internal driver commands (SYNC_DEBUG_BO / ATTACH_DEBUG_BO) legitimately pass AMDXDNA_INVALID_BO_HANDLE, and they always set drv_cmd. Reject the invalid handle for user submissions (drv_cmd == NULL) at the submit choke point so every user path is covered.  Found by 0sec automated security-research tooling (https://0sec.ai).",
