CVE-2025-9071 (GCVE-0-2025-9071)
Vulnerability from nvd – Published: 2025-08-29 09:19 – Updated: 2025-08-29 13:45

Title
Insecure RSA-OAEP implementation with all-zero seed for padding in Oberon PSA Crypto
Summary
Erroneously using an all-zero seed for RSA-OEAP padding instead of the generated random bytes, in Oberon microsystems AG’s Oberon PSA Crypto library in all versions up to 1.5.1, results in deterministic RSA and thus in a loss of confidentiality for guessable messages, recognition of repeated messages, and loss of security proofs.
