CVE-2026-44436: CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in h2o quiclyCVE-2026-44436 0 CVE-2026-44436 is a buffer overflow vulnerability in the quicly library used by the h2o HTTP server. The issue arises because quicly's packet decoder accepts QUIC Connection IDs up to 255 bytes, but its internal buffers for QUIC version 1 are only 20 bytes long. This mismatch can cause connection state corruption and assertion failures, leading to a denial of service. The vulnerability was fixed by commit 8b178e6.
