CVE-2026-59993

The Picotls TLS protocol library is vulnerable to a null-pointer dereference in revisions through 44bc503 when utilized as a client-side TLS stack . An attacker can trigger this by sending a HelloRetryRequest followed by a spoofed Hello message , which can terminate the consuming process and resu...
