One of\nthe errors was fixed by commit ea427a222d8b (\"HID: core: Fix deadloop\nin hid_apply_multiplier.\"), but the other has not been fixed.\n\nThis error arises because hid_apply_multipler() assumes that every\nResolution Multiplier control is contained in a Logical Collection,\ni.e., there's no way the routine can ever set multiplier_collection to\nNULL. This is in spite of the fact that the function starts with a\nbig comment saying:\n\n\t * \"The Resolution Multiplier control must be contained in the same\n\t * Logical Collection as the control(s) to which it is to be applied.\n\t ...\n\t * If no Logical Collection is\n\t * defined, the Resolution Multiplier is associated with all\n\t * controls in the report.\"\n\t * HID Usage Table, v1.12, Section 4.3.1, p30\n\t *\n\t * Thus, search from the current collection upwards until we find a\n\t * logical collection...\n\nThe comment and the code overlook the possibility that none of the\ncollections found may be a Logical Collection.\n\nThe fix is to set the multiplier_collection pointer to NULL if the\ncollection found isn't a Logical Collection." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H", "baseScore": 7.1, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:A - The malformed report descriptor is supplied entirely by the HID device and parsed automatically during enumeration; HID transports include Bluetooth HID/HoGP, making a remote-but-link-local attacker with a rogue HID peripheral a valid vector. This matches the established treatment of other drivers/hid/hid-core.c report-descriptor parsing flaws.\nAC:L - The attacker fully controls the report descriptor and simply omits a Logical Collection around the Resolution Multiplier item, which deterministically drives the collection walk to a non-Logical root every time. No race, timing, or memory-layout condition is involved.\nPR:N - No credentials or privileges on the target are needed — hid_open_report() runs from the enumeration/probe worker as soon as the device is attached or connects, before any userspace authorization. Locally, /dev/uhid offers the same descriptor-injection path.\nUI:N - Report descriptor parsing and hid_setup_resolution_multiplier() are invoked automatically on device attach/connect and again from hidinput_change_resolution_multipliers(); no victim action is required once the device is in range or plugged in.\nS:U - The mishandling and its consequences are confined to the kernel's HID subsystem and the input events it emits — the same security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:N - The defect only causes a pointer to reference a valid-but-wrong collection entry; no out-of-bounds read occurs and no kernel memory contents or addresses are exposed to the attacker or to userspace.\nI:L - The kernel SET_REPORTs the device's Resolution Multiplier to logical_maximum but then fails to divide by it, so wheel/scroll values delivered to userspace are scaled by an attacker-chosen factor of up to 255x. This is corruption of data crossing into userspace, but gives no arbitrary-write or control-flow primitive.\nA:H - This commit is the designated fix for syzbot report ec5f884c4a135aa0dbb9, \"INFO: rcu detected stall in hub_event\" — a kernel hang in the USB enumeration worker triggered by a crafted HID descriptor reaching this Resolution Multiplier code. A stall of the hub_event work queue blocks device enumeration and is a complete availability loss." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected",
