  "details": "In the Linux kernel, the following vulnerability has been resolved:  HID: core: clamp report_size in s32ton() to avoid undefined shift  s32ton() shifts by n-1 where n is the field's report_size, a value that comes directly from a HID device.  The HID parser bounds report_size only to \u003c= 256, so a broken HID device can supply a report descriptor with a wide field that triggers shift exponents up to 256 on a 32-bit type when an output report is built via hid_output_field() or hid_set_field().  Commit ec61b41918587 (\"HID: core: fix shift-out-of-bounds in hid_report_raw_event\") added the same n \u003e 32 clamp to the function snto32(), but s32ton() was never given the same fix as I guess syzbot hadn't figured out how to fuzz a device the same way.  Fix this up by just clamping the max value of n, just like snto32() does.",
