Local access to the machine is required.\nAC:L - On a system in the affected configuration the out-of-bounds `node_to_cpumask_map[-1]` read occurs deterministically on every probe, and the follow-on procfs read that dereferences the poisoned pointer is a plain file read the attacker can repeat at will with no race or timing dependency.\nPR:L - The corrupted `irq_desc::affinity_hint` is installed by the system itself during ordinary boot without any attacker action; dereferencing it only requires reading world-readable (0444) `/proc/irq/\u003cN\u003e/affinity_hint`, which any unprivileged local account can do.\nUI:N - The vulnerable state is established automatically at driver probe, and the attacker triggers the dereference himself via a procfs read \u2014 no victim action of any kind is needed.\nS:U - The out-of-bounds read, the wild dereference, and its effects are all confined to the kernel\u0027s own security authority with no crossing into a hypervisor, IOMMU, or other domain.\nC:H - An uncontrolled value adjacent to `node_to_cpumask_map` is treated as a `struct cpumask *`, and `cpumask_copy()` reads `nr_cpu_ids` bits from that arbitrary kernel address straight into a bitmap printed to unprivileged userspace \u2014 kernel memory disclosure, not a strictly bounded few-byte read.\nI:L - No out-of-bounds write or control-flow hijack primitive exists; the only modification is that MSI-X affinity for the eight high-IOPS storage vectors gets programmed from an uncontrolled mask, misconfiguring interrupt routing on the system\u0027s RAID controller.\nA:H - Dereferencing an arbitrary, potentially unmapped value as a cpumask inside `raw_spinlock_irq` with interrupts disabled can oops or panic the kernel, and the storage controller\u0027s interrupt affinity can be left broken."
