"value": "AV:L - The vulnerable code is `axp20x_probe()`, a platform-driver probe reached at boot or via local module load / sysfs driver bind on an AXP717-equipped board; there is no network, adjacent-network, or physical-insertion path since the PMIC is soldered on-board.\nAC:L - The missing sentinel is unconditional — every probe of the axp717-adc cell deterministically runs the out-of-bounds walk past `axp717_maps[]`; there is no race to win and no state the attacker must wait for.\nPR:L - The out-of-bounds read and the poisoning of the global `iio_map_list` happen during normal boot-time probe without any privileged operation being performed, so an unprivileged local user is exposed to the corrupted state without holding any capability.\nUI:N - The bug fires automatically when the MFD core instantiates the axp717-adc cell during boot; no victim action, mount, or file open is needed.\nS:U - The out-of-bounds read, the corrupted global list, and the resulting wild-pointer dereference all occur within the kernel's own security authority with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - This is an unbounded global out-of-bounds read that walks forward through kernel `.data` until it chances upon a NULL, and the OOB-derived pointers are then dereferenced as strings by `strcmp()` in `iio_channel_get_sys()`/`iio_channel_get_all()`, reading arbitrary kernel memory rather than a strictly bounded few bytes.\nI:L - The bug permanently injects bogus entries built from out-of-bounds memory into the global `iio_map_list` and propagates a garbage `consumer_data` pointer to consumer drivers, corrupting kernel state; it is limited rather than High because the array is only read — there is no out-of-bounds write or control-flow-hijack primitive on this path.\nA:H - The registered garbage entries carry non-string values (e.g. `struct platform_driver` function pointers or arbitrary `.data` words) that `strcmp()` later dereferences, producing an oops or panic, and on a KASAN kernel the global-out-of-bounds report itself panics under `panic_on_warn`."
