      "title": "HID: core: fix number/pointer type confusion on long items",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: core: fix number/pointer type confusion on long items\n\nWhen fetch_item() is called by hid_scan_report() on an item with\nHID_ITEM_TAG_LONG, it stores a pointer to the item data in\nitem->data.longdata instead of storing a value directly in\nitem->data.{u8/u16/u32}.\n\nWhen item_udata() or item_sdata() encounters such an item, it incorrectly\nassumes that the item is in short format, and therefore returns the lower\npart of a kernel pointer reinterpreted as a number.\n\nWhen a HID device is connected whose descriptor contains a\nHID_GLOBAL_ITEM_TAG_REPORT_SIZE encoded in long format with size=4, this\ncauses the lower half of a kernel pointer to be printed into dmesg as a\nnumber, like this:\n\n    hid (null): invalid report_size 107953555\n\nTo fix it, let item_udata() and item_sdata() verify that the item is in\nshort format.\n\nNote that this bug only affects hid_scan_report(), while the main parsing\npass hid_parse_collections() will always bail out when encountering a long\nitem.\n\nSidenote: There are currently no users of data.longdata; maybe we should\njust remove any parsing of long-format descriptors as a follow-up.",
