CVE-2026-53169

In the Linux kernel, accel/ethosu has been fixed to reject NPU_OP_RESIZE commands from userspace. The driver previously used an unconditional WARN_ON(1) in DRM_IOCTL_ETHOSU_GEM_CREATE, enabling kernel log spam and, if panic_on_warn was set, potential DoS via a local unprivileged user. The patch r...
