- Summary
- accel/ethosu: reject NPU_OP_RESIZE commands from userspace
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
accel/ethosu: reject NPUOPRESIZE commands from userspace
NPUOPRESIZE is a U85-only command that the driver does not yet implement. The existing WARNON(1) placeholder fires unconditionally whenever userspace submits this command via DRMIOCTLETHOSUGEM_CREATE, causing unbounded kernel log spam.
If paniconwarn is set the kernel panics, giving any unprivileged user with access to the DRM device a trivial denial-of-service primitive.
Replace the WARN_ON(1) with an explicit -EINVAL return so the ioctl rejects the command before it reaches hardware.
