"value": "AV:L - The vulnerable code is a PCI/auxiliary-bus camera driver probe path, and the resulting corrupted global PM-QoS list is exercised through local interfaces (ALSA PCM ioctls, DRM ioctls, cpuidle). There is no network-reachable path to either the corruption or its exploitation.\nAC:L - On an affected system the dangling plist node is established deterministically during boot whenever isys_probe() fails (the reported real-world case on Intel IPU6 laptops), and from there the attacker's steps — heap-spraying the freed devres allocation and issuing SNDRV_PCM_IOCTL_HW_PARAMS to force plist_add() — are fully repeatable with no race to win and no memory layout the attacker cannot influence.\nPR:L - A plain unprivileged local user account suffices: /dev/snd PCM hw_params reaches cpu_latency_qos_add_request() directly, and heap spraying of the freed kmalloc object needs no capabilities. No root, CAP_SYS_ADMIN, or namespace privileges are required.\nUI:N - The corrupted global PM-QoS list already exists after boot on the affected configuration, and the attacker triggers traversal of it entirely on their own via ordinary ioctls. No victim action is needed.\nS:U - The use-after-free and any resulting privilege escalation are confined to the kernel of the same machine, managed by a single security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free on a globally reachable list node; plist_add()/plist_del() dereference attacker-controlled pointers read out of the reclaimed object, yielding arbitrary kernel memory reads and disclosure of freed-object/kernel-pointer contents.\nI:H - With the freed object reclaimed by attacker-controlled data, plist_add()'s list_add_tail() writes list pointers into attacker-chosen kernel addresses (CONFIG_DEBUG_LIST is off on production kernels), giving a write-what-where primitive suitable for control-flow hijack and privilege escalation.\nA:H - The corrupted plist is walked under the pm_qos_lock raw spinlock by many subsystems, so it reliably produces list-corruption WARNINGs, oopses, or an unrecoverable hard lockup — the reporter observed exactly this crash path from i915's DP AUX transfer."
