  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: pidff: fix OOB write when hid-\u003einputs is empty\n\nhid_pidff_init_with_quirks() derives its input_dev from\n\n\tlist_entry(hid-\u003einputs.next, struct hid_input, list)\n\nwithout first checking that hid-\u003einputs is non-empty.  The list member\nof struct hid_input is at offset 0, so on an empty list list_entry()\nyields \u0026hid-\u003einputs itself and the following hidinput-\u003einput load reads\nan unrelated member of struct hid_device.  dev is then a type-confused\npointer, and force-feedback init writes through it: each\nset_bit(FF_*, dev-\u003effbit) stores 8 bytes at dev + 192, past the end of\nthe object dev actually aliases, and input_ff_create() adds further\nwrites of a heap pointer and two function pointers.\n\nUntil hid-universal-pidff the only caller was hid_pidff_init() from\nusbhid, which runs under HID_CLAIMED_INPUT and therefore always has at\nleast one hid_input.  universal_pidff_probe() starts the device with\nHID_CONNECT_DEFAULT \u0026 ~HID_CONNECT_FF and then calls\nhid_pidff_init_with_quirks() directly whenever the descriptor carries a\nPID usage page, bypassing that gate.  A report descriptor whose only\napplication collection is on HID_UP_PID leaves hid-\u003einputs empty while\nhid_connect() still succeeds through the hidraw claim, so probe reaches\nthe unguarded list_entry().\n\nThe write happens in the USB probe path, on the hotplug workqueue, so\nplugging in a malicious device is enough to trigger it; no attacker\nsoftware and no logged-in user are required.  KASAN reports an 8-byte\nout-of-bounds write in hid_pidff_init_with_quirks() reached from\nuniversal_pidff_probe().\n\nCheck for an empty list before deriving dev and return -ENODEV, as the\nother HID force-feedback drivers already do.  universal_pidff_probe()\npropagates the error and unwinds.\n\nDiscovered by XBOW, triaged by Baul Lee \u003cbaul.lee@xbow.com\u003e",
