CVE-2026-72092

Estado: RecibidaSin puntuar—

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->dev_info->ops->cmd_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.
