Description
In the Linux kernel, the following vulnerability has been resolved:
accel/ethosu: reject NPU_OP_RESIZE commands from userspace
NPU_OP_RESIZE is a U85-only command that the driver does not yet
implement. The existing WARN_ON(1) placeholder fires unconditionally
whenever userspace submits this command via DRM_IOCTL_ETHOSU_GEM_CREATE,
causing unbounded kernel log spam.
If panic_on_warn 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.
Affected configurations
• linux linux kernel (>= 6.19 < 7.0.13)
• linux linux kernel 7.1
