"value": "AV:L - No network or USB packet handler reaches the faulty reference release. Exploitation requires local interaction with the platform-driver lifecycle or subsequent local use of the dangling kernel objects.\nAC:L - On an affected non-OF deployment, probe-error cleanup or driver removal deterministically drops a reference that was never acquired. No race must be won, and heap reclaim can be attacker-groomed.\nPR:L - Although manual unbind or module removal requires init-namespace administration, the same release occurs during automatic probe-failure cleanup. A basic local user can groom and exercise the resulting published dangling I2C and USB-PHY objects.\nUI:N - Probe and cleanup can occur automatically without a victim performing an action. Subsequent exploitation of the dangling objects requires no user interaction.\nS:U - The corruption affects the kernel and resources governed by the same system security authority. It does not cross a VM, IOMMU, or comparable isolation boundary.\nC:H - The release frees the I2C client and devres-managed ISP1301 object while global pointers and I2C and USB-PHY lists still reference them. Reclaiming these objects can expose arbitrary kernel memory through attacker-shaped stale pointers.\nI:H - Dangling klist operations can modify reclaimed memory, while a reclaimed client can supply a forged adapter and indirect I2C algorithm callbacks. This can provide arbitrary writes and kernel control-flow hijacking.\nA:H - Traversal or use of the dangling client, device-private nodes, or USB-PHY list entry can cause an immediate kernel oops, panic, or invalid function call."
