Privileged code execution via unverified DataStore contents
Published Aug 12, 2026 · Updated Aug 12, 2026
Integrity validation failure in CPSD CryptoPro Secure Disk for BitLocker before 7.7.4 allows local users to execute privileged code. The pre-boot environment mounts and processes the non-partitioned DataStore filesystem without authenticating its contents, so modified configuration or cryptographic data is trusted. Exploitation requires local write access to the on-disk DataStore; crafted contents can interrupt service or execute code in a high-privilege context.
