"value": "AV:L - The vulnerability is reached through local FUSE filesystem operations and io_uring commands on a connected /dev/fuse descriptor; no remote protocol reaches this path.\nAC:L - Once FUSE-over-io_uring is enabled, a malicious daemon controls buffer validity, request generation, and commit IDs, allowing it to trigger the dangling entry without winning an uncontrolled race.\nPR:L - FUSE supports user-namespace mounts, and namespace CAP_SYS_ADMIN is sufficient where /dev/fuse is accessible. 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."
