Use of RSA Algorithm without OAEP Affecting nrfconnect/sdk-oberon-psa-crypto package, versions [0,]
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2025-9071 (opens in a new tab)How to fix?
There is no fixed version for nrfconnect/sdk-oberon-psa-crypto.
Overview
Affected versions of this package are vulnerable to Use of RSA Algorithm without OAEP due to the use of an all-zero seed for RSA-OAEP padding. An attacker can compromise the confidentiality of encrypted messages by exploiting the deterministic nature of the encryption, allowing recognition of repeated or guessable messages.
