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.","cvssScore":4.1,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-92382","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2535972","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"The flaw allows an out-of-bounds write by exploiting a usbredir isochronous OUT stream, potentially leading to arbitrary code execution or data corruption.","exploitability":"Exploitation requires specific USB device interaction and knowledge of the vulnerability; it is moderately difficult.","blast_radius":"If exploited, the impact could be significant, including loss of system integrity or unauthorized access.","remediation":"Update to a patched version of usbredir as soon as possible.","tags":["usb","buffer-overflow","security"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-22T06:35:51.629Z"}}
