CVE-2026-108982

Quick assessment

Affected
IDRIX VeraCrypt
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

macOS 平台上的 VeraCrypt 1.26.29（FUSE-T 构建版）存在一个漏洞，可能导致解密数据被非预期访问。当卷（volume）卸载时，VeraCrypt 未终止 FUSE-T 辅助服务（go-nfsv4）及其关联的 VeraCrypt 核心服务辅助进程。在 VeraCrypt 报告卷已卸载后，该辅助挂载仍通过本地回环（loopback）SMB 会话继续提供解密后的卷映像（volume.dmg）。泄露出的辅助进程仍保持对底层原始设备的打开句柄。因此，本地用户或进程可以无需密码即可重新挂载并访问解密卷

Vulnerability Description
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.)
