It does not terminate the FUSE-T auxiliary service (go-nfsv4) and its associated VeraCrypt core-service helper processes when a volume is dismounted. After VeraCrypt reports the volume as dismounted, the auxiliary mount continues to serve the decrypted volume image (volume.dmg) over a loopback SMB session, and the leaked processes retain an open handle to the underlying raw device. A local user or process can therefore remount and access the decrypted volume without the passphrase, e.g., by reopening a previously accessed path (such as through a macOS Open Recent menu) or by attaching volume.dmg from the stale auxiliary mount. (The macFUSE build of VeraCrypt is not affected.)" } ], "metrics": [ { "cvssV4_0": { "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "Safety": "NOT_DEFINED", "attackComplexity": "LOW", "attackRequirements": "PRESENT", "attackVector": "LOCAL", "baseScore": 7.2, "baseSeverity": "HIGH", "privilegesRequired": "LOW", "providerUrgency": "NOT_DEFINED", "subAvailabilityImpact": "NONE", "subConfidentialityImpact": "NONE", "subIntegrityImpact": "NONE", "userInteraction": "NONE", "valueDensity": "NOT_DEFINED", "vectorString": "CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N", "version": "4.0", "vulnAvailabilityImpact": "NONE", "vulnConfidentialityImpact": "HIGH", "vulnIntegrityImpact": "HIGH", "vulnerabilityResponseEffort": "NOT_DEFINED" }, "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ] } ], "problemTypes": [ { "descriptions": [ { "cweId": "CWE-459", "description": "CWE-459 Incomplete Cleanup", "lang": "en", "type": "CWE" } ] } ], "providerMetadata": { "orgId": "8254265b-2729-46b6-b9e3-3dfca2d5bfca", "shortName": "mitre", "dateUpdated": "2026-10-15T02:49:02.840Z" }, "references": [ { "name": "Original public report (June 2026) with maintainer acknowledgment and diagnosis", "url": "https://github.com/veracrypt/VeraCrypt/issues/1779" }, { "name": "Independent report with first process-level diagnosis and maintainer reply (June 2026)", "url": "https://sourceforge.net/p/veracrypt/discussion/general/thread/57f938df8b/" }, { "name": "Consolidated issue: reproductions, lsof evidence, kernel panic analysis, status", "url": "https://github.com/veracrypt/VeraCrypt/issues/1845" }, { "name": "Community fix: terminate auxiliary FUSE-T service on dismount", "url": "https://github.com/veracrypt/VeraCrypt/pull/1866" }, { "name": "Affected release 1.26.29", "tags": [ "product" ], "url": "https://github.com/veracrypt/VeraCrypt/releases/tag/VeraCrypt_1.26.29" }, { "url": "https://github.com/veracrypt/VeraCrypt/security/advisories/GHSA-f3px-f8h2-fm4c" }, { "url": "https://github.com/veracrypt/VeraCrypt/commit/d7bc65bed004996d299ec76666d1b283a07e2526" } ], "solutions": [ { "lang": "en", "supportingMedia": [ { "base64": false, "type": "text/html", "value": "No fixed release as of 2026-10-11.
