CVE-2026-108982

CVSS 7.2 (high) · published 2026-10-12

VeraCrypt 1.26.29 (FUSE-T build) on macOS sometimes allows unintended access to decrypted data. 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.)
