CVE-2026-47703

AdGuard Home is a network-wide software for blocking ads and tracking. Prior to 0.107.75, AdGuard Home's client-triggered DoQ forwarding path to a udp:// upstream reduced backend UDP DNS state by producing dnsid=0 or txid=0 and exposed a quoted-port ICMP source-port oracle, weakening DNS response...

CVE-2026-47703

Summary: CVE-2026-47703 affects AdGuard Home and its DoQ-to-UDP forwarding path. Prior to version 0.107.75, the backend UDP path could collapse the DNS transaction ID (txid) to 0 on client-triggered DoQ queries, reducing the entropy of the backend tuple from (txid, source-port) to only the source...

CVE-2026-40898

A flaw was found in quic-go, an implementation of the QUIC protocol in Go. A remote attacker can exploit this by sending specially crafted HTTP/3 trailer fields. This can cause the system to allocate excessive memory, leading to a denial-of-service DoS condition where the affected server or clien...

CVE-2026-11352

A flaw was found in curl and libcurl. A malicious HTTP/3 server can exploit an issue in the QUIC UDP receive function by continuously streaming empty UDP datagrams. This can lead to a remote denial of service DoS against a curl or libcurl client, as the helper function discards zero-length UDP...

CVE-2026-11352 QUIC zero-length UDP datagrams busy-loop

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...

CVE-2026-11352

The CVE-2026-11352 issue affects curl/libcurl: a bug in the QUIC UDP receive path discards zero-length UDP datagrams instead of counting them toward the per-call budget, enabling a connected HTTP/3 peer to continuously send empty datagrams and cause a remote denial-of-service against curl or libc...
