CVE-2026-63074: Openssl Cmp Uncached Extracerts Leak
Incoming CMP extra certificates are added to the untrusted certificate stack but are only purged when caching is explicitly disabled. If validation fails, these certificates remain cached in the context indefinitely, leading to unbounded memory growth and denial of service. Ensure extra certificates are also removed when validation fails.
