Red Hat Security Advisory: Red Hat OpenShift Service Mesh 3.1.5
Red Hat OpenShift Service Mesh 3. 1. 5 addresses security vulnerabilities related to excessive resource consumption and unbounded memory allocation in components based on the Istio project. The update includes fixes for CVE-2025-61729, which involves excessive resource consumption during error string printing for host certificate validation, and CVE-2025-58183, which involves unbounded allocation when parsing GNU sparse maps. These issues could lead to resource exhaustion in affected components. The advisory indicates that the update to version 3. 1. 5 includes these security fixes and improvements.
AI Analysis
Technical Summary
Red Hat OpenShift Service Mesh 3.1.5, built on Istio 1.26.8, fixes two main security issues: CVE-2025-61729, which causes excessive resource consumption when printing error strings related to host certificate validation in crypto/x509 across multiple components (istio-rhel9-operator, istio-pilot-rhel9, istio-cni-rhel9), and CVE-2025-58183, which causes unbounded memory allocation when parsing GNU sparse maps in istio-cni-rhel9. These vulnerabilities could lead to denial of service conditions due to resource exhaustion. The update also includes other improvements such as OCSP memory leak checks and BSSL compatibility.
Potential Impact
The vulnerabilities can cause excessive resource consumption or unbounded memory allocation in key components of Red Hat OpenShift Service Mesh, potentially leading to denial of service or degraded performance. There are no known exploits in the wild at the time of the advisory. The issues affect the crypto/x509 certificate validation process and parsing of GNU sparse maps, which are critical for secure and stable operation of the service mesh components.
Mitigation Recommendations
Red Hat has released OpenShift Service Mesh version 3.1.5 which includes fixes for these vulnerabilities. Users should upgrade to this version to remediate the issues. The vendor advisory (RHSA-2026:3108) confirms that the update addresses the security flaws. No additional mitigation steps are indicated beyond applying the official update.
