CVE-2025-27580 (GCVE-0-2025-27580)
Vulnerability from cvelistv5 – Published: 2025-04-23 00:00 – Updated: 2025-04-24 14:56
VLAI
Summary
NIH BRICS (aka Biomedical Research Informatics Computing System) through 14.0.0-67 generates predictable tokens (that depend on username, time, and the fixed 7Dl9#dj- string) and thus allows unauthenticated users with a Common Access Card (CAC) to escalate privileges and compromise any account, including administrators.

Title
Fault injection attack with ML-DSA and ML-KEM on ARM
Summary
Protection mechanism failure in wolfCrypt post-quantum implementations (ML-KEM and ML-DSA) in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during Keccak-based expansion.
This issue affects wolfSSL (wolfCrypt): commit hash d86575c766e6e67ef93545fa69c04d6eb49400c6.

CVE-2026-41564 (GCVE-0-2026-41564)

Title
CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking
Summary
CryptX versions before 0.088 for Perl do not reseed the Crypt::PK PRNG state after forking.
The Crypt::PK::RSA, Crypt::PK::DSA, Crypt::PK::DH, Crypt::PK::ECC, Crypt::PK::Ed25519 and Crypt::PK::X25519 modules seed a per-object PRNG state in their constructors and reuse it without fork detection. A Crypt::PK::* object created before `fork()` shares byte-identical PRNG state with every child process, and any randomized operation they perform can produce identical output, including key generation. Two ECDSA or DSA signatures from different processes are enough to recover the signing private key through nonce-reuse key recovery.
This affects preforking services such as the Starman web server, where a Crypt::PK::* object loaded at startup is inherited by every worker process.
