CVE-2026-32665

A flaw was found in Unbound when DNS-over-QUIC DoQ is enabled. An attacker could exploit improper validation of client-provided data length, leading to excessive memory allocation. This can cause the system to exceed its configured memory limits for QUIC connections, resulting in a Denial of...

SUSE CVE-2026-14586

In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, in DNS-over-QUIC environments, with high concurrency and under pressure, an assertion in libngtcp2 about monotonic timestamps could trigger and result in server termination and thus denial of service. When interfacing with libngtcp2, for...

SUSE CVE-2026-32665

In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, when downstream DNS-over-QUIC DoQ is enabled, the first two bidirectional streams on a new QUIC connection streamid 0 and 4 bypass the per-stream 'quic-size' gate entirely, and large input buffers are allocated later, after only the 2-byte...

SUSE CVE-2026-41637

In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, client terminated DNS-over-QUIC DoQ queries are not accounted properly by Unbound resulting in low-cost inflation of the waiting number of replies for already in-flight resolution queries. This results in degradation of resolution service f...

SUSE CVE-2026-55991

In NLnet Labs Unbound 1.22.0 up to and including 1.25.1, a remote unauthenticated client can trigger a libngtcp2 assertion if compiled with assertions on and terminate the entire Unbound process using a single DNS-over-QUIC DoQ connection and one normal DNS query. This is caused by an erroneous...

CVE-2026-66374

Knot Resolver is affected by a heap-based buffer overflow in the DoQ (DNS-over-QUIC) receive path that allows remote code execution on versions prior to 6.4.1. The vulnerability arises in the handling of DoQ traffic, enabling an attacker to trigger arbitrary code execution through crafted input s...
