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.

NewCVE-2025-9230 (opens in a new tab)How to fix?
Upgrade openssl to version 3.0.18, 3.2.6, 3.3.5, 3.4.3, 3.5.4 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the kek_unwrap_key() function. An attacker can cause application instability, crash, or potentially execute arbitrary code by sending CMS messages encrypted using password based encryption to trigger out-of-bounds memory access during.
Note:
This is only exploitable if password-based CMS encryption (PWRI) is enabled and used in the deployment. The FIPS modules in 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue, as the CMS implementation is outside the OpenSSL FIPS module boundary.
OpenSSL premium support customers have an option to upgrade to 1.0.2zm and 1.1.1zd versions to fix this issue.
