CVE-2026-46276

CVE-2026-46276 concerns the Linux kernel AMDGPU driver on RDNA4 (GFX 12). The issue: amdgpu_ttm_init_on_chip() is called for GDS, GWS and OA resources regardless of whether they exist; when a resource size is zero, drm_mm_init(0,0) triggers DRM_MM_BUG_ON and can crash the kernel during modprobe o...
