Last modified

CVE-2025-9071 is a low-severity vulnerability rated 2.3/10 on the CVSS scale. 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.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
