Detailed vulnerability description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper handling of an unimplemented command in DRM_IOCTL_ETHOSU_GEM_CREATE when processing a userspace NPU_OP_RESIZE command. A local user can submit a specially crafted ioctl request to cause a denial of service.
The issue can trigger unbounded kernel log spam, and systems configured with panic_on_warn enabled may panic. Access to the DRM device is required.
