No remote or adjacent-network input reaches it.\nAC:L - Triggering requires the adapter re-init to hit an allocation failure at `aac_comm_init()`/`aac_fib_setup()` while a probe or host-reset is in flight; an attacker able to invoke the reset path can loop it while driving DMA32 memory pressure, controlling both sides and retrying until the ENOMEM window lands.\nPR:L - Once `dev->queues` is left dangling, any local user can drive the paths that dereference and re-free it (ioctl handling, I/O to the array); a plain unprivileged local account is sufficient to supply the memory pressure and to reuse the freed slab object.\nUI:N - No victim action is needed — the free and the subsequent reuse/second free happen inside the driver's own error unwind and interrupt/kthread contexts.\nS:U - The corruption is confined to kernel slab memory managed by the same kernel security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale `dev->queues` is read by the interrupt handlers, the command kthread, and the ioctl path after the object is freed, and the double free lets an attacker place a controlled object at that address — yielding disclosure of arbitrary reallocated kernel data.\nI:H - Freed memory is written through the dangling pointer (queue head/tail indices, list_head links, atomics) and the double free hands the attacker the classic two-owners-of-one-slab-object primitive, which is escalatable to arbitrary kernel write and control-flow hijack.\nA:H - A `kfree()` of an already-freed pointer trips SLUB freelist-hardening `BUG()` or corrupts the freelist, and the dangling `dev->queues` dereference from interrupt context reliably oopses — a full kernel panic on the storage controller." } ] } ], "affected": [ { "product": "Linux",
