Secret-key disclosure via unchecked faulty decryptions
Published May 13, 2024 · Updated Feb 13, 2025
Fault injection in Crypto++ 8.9.0 ElGamal decryption allows local users to recover secret keys from faulty plaintext outputs. SymmetricDecrypt uses a potentially bit-flipped secret key to compute the modular inverse and returns the resulting plaintext without a consistency check. Exploitation requires a co-resident process to induce Rowhammer faults and obtain enough faulty decryption outputs for key recovery.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
