Red Hat Security Advisory: nodejs24 security update
Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Security Fix(es): * nodejs: Nodejs filesystem permissions bypass (CVE-2025-55132) * nodejs: Nodejs denial of service (CVE-2026-21637) * nodejs: Nodejs denial of service (CVE-2025-59466) * nodejs: Nodejs denial of service (CVE-2025-59465) * nodejs: Nodejs uninitialized memory exposure (CVE-2025-55131) * nodejs: Nodejs file permissions bypass (CVE-2025-55130) 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.
AI Analysis
Technical Summary
This advisory covers multiple security vulnerabilities in the nodejs24 package for Red Hat Enterprise Linux 10, including CVE-2025-55130 and five others. The vulnerabilities include filesystem permissions bypass (CVE-2025-55130, CVE-2025-55132), denial of service (CVE-2026-21637, CVE-2025-59465, CVE-2025-59466), and uninitialized memory exposure (CVE-2025-55131). These issues could allow unauthorized access to filesystem permissions, cause denial of service conditions, or expose uninitialized memory. Red Hat has released updated packages to address these vulnerabilities across multiple architectures and support levels of Red Hat Enterprise Linux 10.
Potential Impact
The vulnerabilities could allow attackers to bypass filesystem permissions, cause denial of service, or expose uninitialized memory in Node.js applications running on affected Red Hat Enterprise Linux 10 systems. This may lead to unauthorized access to files, application crashes, or potential information disclosure. The advisory rates the overall impact as important with a high severity level.
Mitigation Recommendations
Red Hat has released updated nodejs24 packages for Red Hat Enterprise Linux 10 and its extended support versions that fix these vulnerabilities. Users should apply the security update as described in the Red Hat advisory RHSA-2026:1842 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official update.
