"HIGH"}, "scenarios": [{"lang": "en", "value": "AV:L - The OOB is in software_node_get_reference_args() in drivers/base/swnode.c, reached only from in-kernel fwnode_property_get_reference_args()/fwnode_find_reference() on local probe/consumer paths (led_get \u2192 fwnode_led_get, swnode_gpio_get_reference, IIO/reset/mailbox); the wrapping index is a kernel argument, not bytes from a packet or remote peer.\nAC:H - Only index==UINT_MAX makes (index+1)*sizeof(*ref) wrap to 0 so the bound is skipped. led_get() passes -1 into fwnode_led_get(), but that value is overwritten by fwnode_property_match_string() for every in-tree con_id (v4l2_subdev_get_privacy_led \"privacy\", yogabook \"pen-icon-led\"); other negative errnos do not wrap on 64-bit, so the attacker cannot force UINT_MAX against a live DEV_PROP_REF.\nPR:L - The lookup runs in driver probe and consumer helpers (led_get from v4l2_subdev_get_privacy_led, swnode_find_gpio, fwnode_find_reference) with no capability check; an unprivileged local user can provoke those paths by opening a consumer device node or causing bind, without init-namespace root or user-namespace tricks.\nUI:N - software_node_get_reference_args() runs automatically inside fwnode_find_reference()/led_get()/swnode_gpio_get_reference during probe or consumer get; no other user must mount media, open a file, or confirm a prompt.\nS:U - The wild software_node_ref_args load, fwnode_handle_get() and any oops stay inside the host kernel; no VM, IOMMU or sandbox boundary is crossed.\nC:H - ref=&ref_array[UINT_MAX] reads a full software_node_ref_args (swnode, fwnode, nargs, args[NR_FWNODE_REFERENCE_ARGS]) from wrapped/wild memory; those pointers and u64 args[] are not a few bounded bytes and can be returned to GPIO/LED/IIO consumers.\nI:H - The OOB bytes are used as ref->swnode/ref->fwnode; software_node_fwnode() or fwnode_handle_get() then software_node_get() \u2192 kobject_get() runs on that pointer, an ops-vtable call and a refcount write at a non-object address \u2014 a control-flow-relevant primitive.\nA:H - The wrapped ref_array[UINT_MAX] pointer is immediately dereferenced (ref->swnode / ref->fwnode / fwnode_handle_get()), which oopses or panics the kernel (KASAN slab-OOB or wild-pointer fault)."}]}], "affected": [{"product": "Linux", "vendor": "Linux",
