CVE-2025-59464

HIGH

Nodejs Node.js < 24.12.0 - Denial of Service

Title source: rule
STIX 2.1

Description

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.
