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.","state":0,"publishedAt":"2026-09-04T18:34:30.258+00:00","modifiedAt":"2026-10-01T19:19:33.063+00:00","affected":[{"ecosystem":"Vendor product","name":"PerformanceTest","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"vendor\": \"PassMark Software\",\n                    \"product\": \"PerformanceTest\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"11.1 build 1012\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"BurnInTest","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"vendor\": \"PassMark Software\",\n                    \"product\": \"BurnInTest\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"11.1 build 1000\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"OSForensics","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"affected\",\n                    \"vendor\": \"PassMark Software\",\n                    \"product\": \"OSForensics\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThan\": \"11.1 build 1016\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://github.com/floppywiggler/directio64-disclosure","https://www.passmark.com/products/performancetest/history.php","https://www.passmark.com/products/burnintest/history.php","https://www.osforensics.com/whats-new.html","https://dkom.dev/posts/directio64-disclosure/","https://www.vulncheck.com/advisories/passmark-performancetest-burnintest-and-osforensics-hard-coded-credentials-authentication-bypass-via-directio64-sys"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-80114","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-80114","identifiers":["CVE-2026-80114"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
