No remote packet or protocol data reaches `lib/cpu_rmap.c`; the RFS receive path only reads `rmap->near[]`, not the freed glue objects.\nAC:L - The use-after-free is deterministic and requires no race \u2014 releasing an IRQ vector leaves a stale `rmap->obj[]` entry that the subsequent `free_irq_cpu_rmap()` walk unconditionally dereferences, and the attacker fully controls the ordering and timing of both steps. `CONFIG_RFS_ACCEL` is `default y` (depends on `RPS`), so the required configuration is the norm on distro kernels, and the unbounded window between free and walk lets the attacker reliably groom the `kmalloc-64` slab.\nPR:L - Triggering requires CAP_NET_ADMIN over the affected netdev (ethtool set-channels, link down, devlink SF removal), which per kernel-CNA guidance scores as Low rather than High. In common SR-IOV/container deployments an mlx5 VF netdev is delegated into a network namespace owned by a user namespace, giving an otherwise unprivileged container-local user exactly this capability over the device.\nUI:N - No victim action is needed; the attacker performs both the IRQ-vector release and the subsequent rmap teardown entirely on their own via device reconfiguration.\nS:U - The freed object, the corrupted state, and the resulting impact are all within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free on a `kmalloc-64` GFP_KERNEL object with an attacker-paced reclaim window, so the freed `struct irq_glue` can be reoccupied with sprayed data; the attacker-controlled `notify.irq` then selects an arbitrary `irq_desc`, and the resulting refcount underflow and indirect `->release` call chain can be leveraged into arbitrary kernel memory disclosure.\nI:H - After reclaiming the freed glue, `irq_set_affinity_notifier(glue->notify.irq, NULL)` performs an arbitrary IRQ-descriptor lookup and issues spurious `kref_put(&old_notify->kref, old_notify->release)` calls on a live notifier, producing refcount underflow, premature free, and an indirect call through a function pointer \u2014 a control-flow hijack primitive rather than a mere crash.\nA:H - Even unweaponized, dereferencing the freed glue and passing garbage to `irq_set_affinity_notifier()` corrupts unrelated IRQ descriptor state and oopses/panics the kernel during device teardown, and the double kref_put can prematurely free the cpu_rmap itself."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git",

will leave the pointer in the array. A\nsubsequent call to free_irq_cpu_rmap() will try to free this entry again\nleading to possible use after free.\n\nFix that by setting NULL to the array entry and checking that we have\nnon-zero at the array entry when iterating over the array in\nfree_irq_cpu_rmap().\n\nThe current code does not suffer from this since there are no cases\nwhere irq_set_affinity_notifier(irq, NULL) (note the NULL passed for the\nnotify arg) is called, followed by a call to free_irq_cpu_rmap() so we\ndon't hit and issue.
