CVE-2025-59319Public exploitNetwork attack vector

Privileged code execution via FIFO partition selection

Published Aug 12, 2026 · Updated Aug 12, 2026

Authentication bypass in CPSD CryptoPro Secure Disk for BitLocker before 7.7.4 allows attackers to execute code with high privilege. Its pre-boot code accepts the first GPT partition bearing a hardcoded EDA type value without verifying that it is the intended trusted partition. An attacker who can alter the disk layout can place a crafted Linux partition earlier in the GPT search order and have it selected at boot.
