RHSA-2026:57021

RHSA-2026:57021 PUBLISHED CVSS 7.5 HIGH

A flaw was found in OpenSSL. A malicious TLS (Transport Layer Security) server can exploit this vulnerability by sending a specially crafted OCSP (Online Certificate Status Protocol) response during the X.509 certificate chain verification process. This can lead to a memory leak in client applications that have enabled OCSP response checking. Repeated connections to a malicious server could exhaust the client's memory, ultimately resulting in a Denial of Service (DoS).
