Attackers can obtain a device handle and write to sensitive ports including the PS/2 controller port, CPU reset ports, CMOS configuration ports, and interrupt controller ports to cause an immediate system reset or other hardware-level manipulation from a standard user account.","published":"2026-09-04T19:17:28.560","modified":"2026-09-04T19:17:28.560","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/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-arbitrary-i-o-port-access-via-directio64-sys"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-04T19:17:28.560"}}
