This Red Hat security advisory addresses three vulnerabilities (CVE-2026-42245, CVE-2026-42246, CVE-2026-42256) affecting ruby3.3 packages included in Red Hat Hardened Images RPMs. The vulnerabilities correspond to CWE-606 and CWE-325, indicating issues with unchecked input in loop conditions and missing cryptographic steps, respectively. The advisory lists updated RPM packages for ruby3.3 and its related gems for aarch64 and x86_64 architectures, as well as noarch packages. While no explicit affected versions are provided, the advisory implies that the updated packages supersede previous vulnerable versions. No known exploits in the wild have been reported. The advisory is published by Red Hat Product Security with a high severity rating but without a CVSS score. Users are directed to Red Hat's image repository for applying the update.

The vulnerabilities addressed involve unchecked input in loop conditions and missing required cryptographic steps, which could potentially lead to security issues such as logic errors or weakened cryptographic protections in ruby3.3 environments. The exact impact details are not specified in the advisory, and no known exploits in the wild have been reported. However, the high severity classification indicates that these issues could pose significant risks if left unpatched.

Red Hat has released updated ruby3.3 RPM packages as part of the Hardened Images update to remediate these vulnerabilities. Users should apply these updated packages from Red Hat's official repositories to mitigate the risks. Since this is an official security advisory with available updates, applying the provided RPM updates is the recommended remediation. No indication is given that no action is required or that the issue is already mitigated.
