There is no network path.\nAC:L - The leak/UAF triggers when xe_dma_buf_init_obj() fails (ENOMEM in bo creation), a condition the attacker can induce via memory pressure and unlimited retries; per the higher-severity rule this is Low.\nPR:L - The PRIME_FD_TO_HANDLE ioctl is DRM_RENDER_ALLOW and the xe driver exposes DRIVER_RENDER render nodes, so any unprivileged local user with render-node access can trigger it. No real root is required.\nUI:N - The attacker performs the prime-import ioctl directly; no victim action is needed.\nS:U - The dangling attachment and freed bo are kernel-internal to the GPU/dma-buf subsystem; the impact stays within the kernel's security authority.\nC:H - The leaked attachment leaves a dangling importer_priv to the freed bo; via the exporter's move_notify path the freed (reallocatable) object is dereferenced, enabling disclosure of attacker-influenced freed-object contents (UAF).\nI:H - The use-after-free allows the freed bo to be reclaimed and controlled via heap spray, after which xe_dma_buf_move_notify()/xe_bo_evict() operate on attacker-controlled memory, yielding a write/control-flow primitive.\nA:H - Dereferencing the freed bo through the leaked attachment's move_notify callback corrupts kernel state and readily causes an oops/panic; the attachment also constitutes a kernel memory leak."
