AZL-92976 CVE-2026-55991 affecting package unbound for versions less than 1.25.2-1

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...

unbound: Unbound: Denial of Service via crafted DNS-over-QUIC connection

A flaw was found in Unbound. A remote, unauthenticated client can exploit this vulnerability by sending a specially crafted DNS-over-QUIC DoQ connection and a single DNS query. This can trigger an assertion failure in the libngtcp2 library, leading to the termination of the entire Unbound process...

CVE-2026-55991

CVE-2026-55991 affects NLnet Labs Unbound 1.22.0–1.25.1. A remote unauthenticated DoQ client can trigger a libngtcp2 assertion by passing an erroneous error value when ngtcp2_conn_writev_stream() returns NGTCP2_ERR_STREAM_DATA_BLOCKED and Unbound calls ngtcp2_ccerr_set_application_error() with -1...
