Technical Summary
The podman tool, part of the libpod library used for container pod management, is affected by two security vulnerabilities. CVE-2025-52881 is a runc vulnerability allowing container escape and denial of service through arbitrary write gadgets and procfs write redirects. CVE-2025-58183 is a golang archive/tar vulnerability causing unbounded memory allocation when parsing GNU sparse maps. Red Hat has issued an important security update for podman in Red Hat Enterprise Linux 10.0 Extended Update Support and related products to fix these issues.
Potential Impact
