CVE-2026-77572

Description

VeraCrypt provides disk encryption with strong security based on TrueCrypt. 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.
