The security advisory from Red Hat addresses denial of service vulnerabilities in Ruby, an extensible, interpreted, object-oriented scripting language. The specific issues fixed include a denial of service in the resolv gem (CVE-2025-24294) and a denial of service in the REXML library (CVE-2025-58767). These vulnerabilities could be exploited to disrupt normal service operation. Red Hat has issued patches for Red Hat Enterprise Linux 10 and associated CodeReady Linux Builder variants across multiple architectures. The advisory references three CVEs and provides updated package versions to remediate the issues.

The vulnerabilities allow denial of service attacks via the resolv gem and REXML library in Ruby. This could result in service disruption or application crashes on affected systems running vulnerable Ruby versions. The security impact is rated as moderate by Red Hat Product Security. There are no known exploits in the wild at the time of the advisory.

Red Hat has released official security updates that fix these vulnerabilities. Users should apply the updated Ruby packages for Red Hat Enterprise Linux 10 and related products as detailed in the Red Hat advisory RHSA-2025:23141. No additional mitigation steps are required beyond applying the official patches.
