TIMELINE Jun 5 Reserved by curl Jul 3 EXPLOIT PUBLISHED — CVE-2026-11352 (curl). Public exploit reference added. Jul 3 Published (CNA: curl)
An issue in curl’s QUIC UDP receive function allows a malicious HTTP/3 server to trigger a remote denial of service against a curl or libcurl client. Because the helper function discards zero-length UDP datagrams before counting them toward the per-call packet budget, a connected QUIC peer can continuously stream empty datagrams to indefinitely stall the client.
