CVE-2025-59464
high
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. Impact: This public CVE is only issued for the affected v24 releases. Thank you, to giant_anteater for reporting this vulnerability and thank you RafaelGSS for fixing it.
