A malicious HID descriptor can advertise a large\nfeature field size while an IIO caller supplies a small stack buffer,\nsuch as a single s32, causing an out-of-bounds write.\n\nHID core stores parsed report values in __s32 slots and clamps extracted\nvalues to 32 bits. Reject feature fields that require more than one slot\nper value, guard the total byte count calculation, and clamp each\nper-value copy to the remaining caller buffer.","state":0,"publishedAt":"2026-09-11T19:46:39.823+00:00","modifiedAt":"2026-10-19T08:51:42.57+00:00","affected":[{"ecosystem":"Vendor
