Overview
CVE-2026-72092 is a known-severity vulnerability. It was published on August 15, 2026.
Technical description
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.

How can CyberStrike help with CVE-2026-72092?
CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-72092 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
