CVE-2026-92382CVE-2026-92382

Description

An out-of-bounds write flaw was found in usbredir. Starting an isochronous OUT stream with a transfer count of 1 leaves the stream's single transfer buffer permanently unsubmitted, defeating the bounds check in usbredirhost_iso_packet() and allowing a usbredir peer to write past the end of the packet descriptor array on every subsequent isochronous packet.
