Attackers can additionally bypass a secondary validation gate by using the driver's own bit-clear IOCTL to clear a single bit in the gating instruction's displacement byte, causing all subsequent write requests to skip MAC verification, size checks, and Vendor ID checks entirely.","published":"2026-09-04T19:17:28.140","modified":"2026-09-04T19:17:28.140","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://dkom.dev/posts/directio64-disclosure/"},{"type":"WEB","url":"https://github.com/floppywiggler/directio64-disclosure"},{"type":"WEB","url":"https://www.osforensics.com/whats-new.html"},{"type":"WEB","url":"https://www.passmark.com/products/burnintest/history.php"},{"type":"WEB","url":"https://www.passmark.com/products/performancetest/history.php"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/passmark-performancetest-burnintest-and-osforensics-hard-coded-credentials-authentication-bypass-via-directio64-sys"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-04T19:17:28.140"}}
