CVE-2026-46276

A flaw was found in the Linux kernel's `amdgpu` graphics driver. This vulnerability occurs when the driver attempts to initialize zero-sized graphics memory resources on certain RDNA4 (GFX 12) hardware. If a specific debugging option (`CONFIG_DRM_DEBUG_MM`) is enabled in the kernel configuration, this improper initialization can lead to a kernel crash, resulting in a denial of service for the system.
