Important: nodejs24 security update (Amazon Linux 2023)

Published Feb 5, 2026 · Updated Feb 5, 2026

Ecosystem: Amazon Linux

Summary

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-22036: Undici is an HTTP/1.1 client for Node.js. Prior to 7.18.0 and 6.23.0, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. This vulnerability is fixed in 7.18.0 and 6.23.0. CVE-2026-21637: TLS PSK/ALPN Callback Exceptions Bypass Error Handlers, Causing DoS and FD Leak NOTE: https://nodejs.org/en/blog/vulnerability/december-2025-security-releases#tls-pskalpn-callback-exceptions-bypass-error-handlers-causing-dos-and-fd-leak-cve-2026-21637---medium CVE-2025-59466: Uncatchable "Maximum call stack size exceeded" error on Node.js via async_hooks leads to process crashes bypassing error handlers CVE-2025-59465: Node.js HTTP/2 server crashes with unhandled error when receiving malformed HEADERS frame CVE-2025-59464: Memory leak that enables remote Denial of Service against applications processing TLS client certificates CVE-2025-55132: fs.futimes() Bypasses Read-Only Permission Model CVE-2025-55131: A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other TypedArray instances like Uint8Array may contain leftover data from previous operations, allowing in-process secrets like tokens or passwords to leak or causing data corruption. While exploitation typically requires precise timing or in-process code execution, it can become remotely exploitable when untrusted input influences workload and timeouts, leading to potential confidentiality and integrity impact. CVE-2025-55130: Bypass File System Permissions using crafted symlinks
