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.","state":0,"publishedAt":"2025-02-27T02:07:10.621+00:00","modifiedAt":"2026-10-15T01:01:13.153+00:00","affected":[{"ecosystem":"Vendor
