NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs-22 package and not the nodejs-22 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

A memory leak in Node.js’s OpenSSL integration occurs when converting X.509 certificate fields to UTF-8 without freeing the allocated buffer. When applications call socket.getPeerCertificate(true), each certificate field leaks memory, allowing remote clients to trigger steady memory growth through repeated TLS connections. Over time this can lead to resource exhaustion and denial of service.
