"value": "AV:L - The vulnerable path is generic block-layer hw-queue reallocation reached through local interfaces — sysfs queue reconfiguration, block ioctls/netlink, device reset, and suspend/resume — with no network-facing parser involved. Even the nvme-oF reconnect angle requires an already-established local block device, so the attack is local.\nAC:L - The reuse of a still-cpuhp-registered hctx is deterministic on any nr_hw_queues update, and the conditions that turn it into a free (allocation failure in blk_mq_init_hctx) or a concurrent callback are attacker-influenceable via memory pressure and repeated queue reconfiguration. Both sides of the race/window are driven by the attacker's own repeated operations.\nPR:L - An unprivileged local user can drive the queue-reallocation path indirectly — inducing NVMe controller resets through I/O timeouts and via logind-permitted suspend/resume (which also mass-offlines/onlines CPUs, walking the corrupted lists) — while supplying the memory pressure needed for the failing-init free. No root-only capability is strictly required for the influencing conditions.\nUI:N - No victim action is needed; the attacker triggers queue reallocation and the subsequent hotplug/list operations entirely through its own activity.\nS:U - The corruption is confined to kernel heap and kernel-global cpuhp instance lists within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The dangling hlist node lets an attacker reallocate the freed blk_mq_hw_ctx slab object and have the kernel traverse attacker-controlled list pointers and dereference hctx->queue in blk_mq_hctx_notify_dead(), yielding an arbitrary kernel-memory read primitive.\nI:H - hlist_add_head() writes a kernel pointer into the freed object and hlist_del() through a reallocated node is a write-what-where; the callback path additionally reaches q->mq_ops indirect calls from freed memory, enabling control-flow hijack and privilege escalation.\nA:H - A use-after-free on globally traversed cpuhp instance lists reliably produces list corruption, oopses, and kernel panics on the next CPU hotplug transition or block-queue setup/teardown."
