High [CVE-2026-11352] Remote denial of service via QUIC UDP receive function vulnerability
CVE-2026-11352Source published Source updated
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. A flaw was found in curl and libcurl. By continuously sending zero-length UDP datagrams, an attacker can indefinitely stall the client, impacting service availability without requiring authentication or user interaction. This poses a significant risk to applications relying on curl for HTTP/3 communication. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-835.
