CVE-2026-44452

CVE-2026-44452 affects the h2o HTTP server (supports HTTP/1.x, 2, 3). Affected behavior occurs when a TLS/QUIC ClientHello contains a zero-length SNI extension; h2o can attempt to copy the hostname assuming NULL-termination, causing a heap/segmentation fault that may enable a denial-of-service. T...
