CVE-2026-108982
VeraCrypt 1.26.29 (compilación FUSE-T) en macOS a veces permite acceso no intencionado a datos descifrados. No finaliza el servicio auxiliar FUSE-T (go-nfsv4) ni sus procesos auxiliares asociados del servicio principal de VeraCrypt cuando se desmonta un volumen. Después de que VeraCrypt informa que el volumen está desmontado, el montaje auxiliar continúa sirviendo la imagen de volumen descifrada (volume.dmg) sobre una sesión SMB de bucle invertido, y los procesos filtrados retienen un identificador abierto al dispositivo sin procesar subyacente.
Leer descripción completaMostrar menos
Por lo tanto, un usuario o proceso local puede remontar y acceder al volumen descifrado sin la contraseña, por ejemplo, reabriendo una ruta previamente accedida (como a través del menú Open Recent de macOS) o adjuntando volume.dmg desde el montaje auxiliar obsoleto. (La compilación macFUSE de VeraCrypt no se ve afectada.)

"value": "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.)"
