* Fix a potential information disclosure in TLS 1.2 servers using session
tickets. If the session ticket write callback failed without setting the
lifetime output parameter, Mbed TLS could send 4 bytes of uninitialized
stack memory to the peer in the NewSessionTicket message. Fixes #1570.
Reported by James Love. CVE-2026-50586.
