Description

A flaw was found in the Linux kernel's accel/ethosu driver. An unprivileged local user with access to the Direct Rendering Manager (DRM) device could submit a specific command (NPU_OP_RESIZE) that the driver does not properly handle. This could lead to excessive kernel log spam and, if the panic_on_warn setting is enabled, cause the kernel to crash, resulting in a denial of service (DoS).
