CVE-2025-59464 (GCVE-0-2025-59464)

Vulnerability from cvelistv5 – Published: 2026-01-20 20:41 – Updated: 2026-01-21 20:41
VLAI?
Summary
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.
Severity ?
6.5 (Medium)
