Prior to version 1.1.5, getSectorSize() in USB Test/src/driveinfo.cpp trusts DISK_GEOMETRY.BytesPerSector returned by IOCTL_DISK_GET_DRIVE_GEOMETRY without checking whether the call succeeded or enforcing size bounds. USB Test/src/drivetest.cpp uses the value for division and to size a heap buffer before memcpy(buffer.data(), &sector, 8), so a physically connected malicious USB storage device can report a value below eight bytes and cause repeated out-of-bounds writes, or report zero and cause a divide-by-zero denial of service when a user starts a drive test. The heap corruption can crash the elevated application and may permit arbitrary code execution. This issue is fixed in version 1.1.5.","state":0,"publishedAt":"2026-10-28T15:42:11.023+00:00","modifiedAt":"2026-10-29T18:37:18.07+00:00","affected":[{"ecosystem":"Vendor product","name":"usb-test","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n-romanovich\",\n                    \"product\": \"usb-test\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.1.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:P/AC:L/AT:N/PR:H/UI:P/VC:N/VI:H/VA:H/SC:N/SI:H/SA:H","score":7,"severity":"HIGH"}],"references":["https://github.com/n-romanovich/usb-test/security/advisories/GHSA-cfrv-c9q2-7cr3","https://github.com/n-romanovich/usb-test/commit/5b6caac844461024520b02337d3a541fbe128f89","https://github.com/n-romanovich/usb-test/releases/tag/release-v1.1.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116776","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116776","identifiers":["CVE-2026-116776"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
