In 1.26.29 and earlier, selected metadata IOCTL handlers in the VeraCrypt Windows veracrypt.sys driver accept caller-supplied object-manager and device paths broader than supported VeraCrypt workflows require. A local user who can open the intentionally user-accessible \\.\\VeraCrypt device can use TC_IOCTL_GET_RESOLVED_SYMLINK, TC_IOCTL_GET_DRIVE_PARTITION_INFO, VC_IOCTL_GET_DRIVE_GEOMETRY_EX, or the legacy TC_IOCTL_GET_DRIVE_GEOMETRY handler to make src/Driver/Ntdriver.c perform kernel-context symbolic-link or disk-device lookups outside the intended path scope. This can disclose low-sensitivity drive-letter targets, partition information, disk geometry, GPT or MBR state, and limited object-manager path metadata.","state":0,"publishedAt":"2026-10-14T15:26:31.329+00:00","modifiedAt":"2026-10-15T15:08:14.109+00:00","affected":[{"ecosystem":"Vendor product","name":"VeraCrypt","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"veracrypt\",\n                    \"product\": \"VeraCrypt\",\n                    \"versions\": [\n                        {\n                            \"version\": \"<= 1.26.29\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","score":3.3,"severity":"LOW"}],"references":["https://github.com/veracrypt/VeraCrypt/security/advisories/GHSA-9mgv-w2fw-3m78","https://github.com/veracrypt/VeraCrypt/commit/ca35405421df549e75f1f241259bdda0c5b67d40","https://github.com/veracrypt/VeraCrypt/releases/tag/VeraCrypt_1.26.29"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77572","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77572","identifiers":["CVE-2026-77572"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
