Red Hat Security Advisory: podman security update
The podman tool manages pods, container images, and containers. It is part of the libpod library, which is for applications that use container pods. Container pods is a concept in Kubernetes. Security Fix(es): * runc: container escape and denial of service due to arbitrary write gadgets and procfs write redirects (CVE-2025-52881) * golang: archive/tar: Unbounded allocation when parsing GNU sparse map (CVE-2025-58183) * github.com/sirupsen/logrus: github.com/sirupsen/logrus: Denial-of-Service due to large single-line payload (CVE-2025-65637) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Technical Summary
The Red Hat security advisory RHSA-2026:4533 details fixes for podman and its dependencies addressing three vulnerabilities: CVE-2025-52881 in runc allows container escape and denial of service via arbitrary write gadgets and procfs write redirects; CVE-2025-58183 in golang's archive/tar causes unbounded memory allocation when parsing GNU sparse maps; and CVE-2025-65637 in github.com/sirupsen/logrus leads to denial of service due to processing large single-line payloads. These vulnerabilities impact container isolation and resource management in podman environments. The advisory applies to Red Hat Enterprise Linux 9.2 versions before 9.2.1 and related packages.
Potential Impact
Successful exploitation of CVE-2025-52881 could allow an attacker to escape container isolation and cause denial of service, compromising container security. CVE-2025-58183 may lead to excessive memory consumption causing denial of service during archive extraction. CVE-2025-65637 can cause denial of service by processing large single-line log payloads. These vulnerabilities collectively affect container runtime security and stability on affected Red Hat Enterprise Linux 9.2 systems.
Mitigation Recommendations
Red Hat has released an updated podman package for Red Hat Enterprise Linux 9.2 (version 9.2.1 and later) that addresses these vulnerabilities. Users should apply the official update as described in the Red Hat advisory RHSA-2026:4533 and the linked article https://access.redhat.com/articles/11258 to remediate these issues. No additional mitigation steps are indicated by the vendor.
