CVE-2026-34183

CVE-2026-34183 affects the OpenSSL QUIC stack’s PATH_CHALLENGE handling. A remote attacker can flood a QUIC client or server with PATH_CHALLENGE frames, causing unbounded heap allocations and potentially Denial of Service. For every PATH_CHALLENGE, the local QUIC stack allocates a PATH_RESPONSE f...

CVE-2026-34183 Unbounded Memory Growth in the QUIC PATH_CHALLENGE Handler
