No capability in the initial user namespace is required.\nUI:N - The attacker can create and operate the FUSE mount, invalidate the registered buffers, and submit subsequent commands without action by another user.\nS:U - Exploitation compromises the host kernel, which is the same security authority in which the vulnerable code executes.\nC:H - The dangling processing-list entry produces a kernel use-after-free whose reclaimed object can be manipulated to disclose arbitrary kernel memory.\nI:H - Deleting or moving the stale list node performs writes through freed or attacker-influenced list pointers, enabling kernel heap corruption and potential control-flow hijacking.\nA:H - The corrupted list and freed request can cause invalid kernel accesses, infinite traversal under a spinlock, an oops, or a kernel panic."
