Technical Summary
This advisory covers Red Hat OpenShift Container Platform 4.12.84, which includes updates to container images and RPM packages that fix multiple security vulnerabilities identified by CVE-2025-4953, CVE-2025-8677, CVE-2025-11561, CVE-2025-40778, CVE-2025-40780, CVE-2025-52881, and CVE-2025-59375. The vulnerabilities affect components such as podman (build context bind mount), expat (large dynamic memory allocations), sssd (Kerberos configuration privilege escalation), runc (container escape and denial of service), and bind (cache poisoning and resource exhaustion). Red Hat rates the overall security impact of this update as Low, despite the individual CVEs being tagged as high severity. The advisory recommends upgrading to 4.12.84 to obtain these fixes. The update is for on-premise or private cloud deployments of OpenShift Container Platform 4.12 on multiple architectures including x86_64, ppc64le, s390x, and aarch64.
Potential Impact
The vulnerabilities fixed in this update include privilege escalation on Active Directory-joined Linux systems, container escape and denial of service via arbitrary write gadgets and procfs write redirects, cache poisoning attacks on DNS, and resource exhaustion via malformed DNSKEY handling. These issues could allow attackers to escalate privileges, escape container isolation, poison DNS caches, or cause denial of service conditions. The overall security impact is rated Low by Red Hat Product Security for this update, but the individual CVEs are considered high severity. No known exploits in the wild have been reported at the time of this advisory.
Mitigation Recommendations
Red Hat OpenShift Container Platform 4.12 users should upgrade to version 4.12.84 to apply the security fixes and bug fixes included in this release. The update is available through the appropriate release channels and can be applied using the OpenShift CLI (oc) or web console.
