Red Hat ships Important Node.js 20 security update for RHEL 9.4
TL;DR — Red Hat shipped an Important-severity advisory updating Node.js 20 on RHEL 9.4 EUS, addressing denial of service, memory exposure, and file permission bypass issues.
What happened
Red Hat published RHSA-2026:2768 (severity: Important) for the nodejs:20 module on RHEL 9.4 Extended Update Support. The advisory addresses three security issues: denial of service (CVE-2025-59465), uninitialized memory exposure (CVE-2025-55131), and a file permissions bypass (CVE-2025-55130).
Distribution-level Node.js patches often lag behind upstream releases — if you're running Node.js from RHEL module streams rather than upstream binaries, this is your signal to patch.
Who is impacted
- Platform teams running RHEL 9.4 EUS with the
nodejs:20runtime for applications or build pipelines. - Developers building services that rely on the distribution-provided Node.js 20 module stream.
What to do now
- Prioritize patching systems using
nodejs:20on RHEL 9.4 EUS. - Apply the Red Hat update as described in the advisory.
- Restart Node.js services and build agents/CI runners to ensure the patched runtime is loaded.
