  "details": "In the Linux kernel, the following vulnerability has been resolved:  accel/amdxdna: reject command submission on devices without a submit op  amdxdna_cmd_submit() calls xdna-\u003edev_info-\u003eops-\u003ecmd_submit() unconditionally, but only aie2_dev_ops defines that callback. aie4_vf_ops (the AIE4 SR-IOV virtual function) does not, so a user AMDXDNA_EXEC_CMD ioctl on an AIE4 device reaches a NULL function-pointer call and oopses the kernel. AIE4 submits work through a mapped user queue and doorbell, not this ioctl path.  Reject the submission early with -EOPNOTSUPP when the device provides no cmd_submit op, so the shared EXEC ioctl is a clean no-op on such devices.
