ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1, ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted peer transport parameters. This issue has been fixed in version 1.22.1. If developers are unable to immediately upgrade, they can disable the qlog on client.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-8300-1 advisory.

    Zou Dikai discovered that ngtcp2 serialized peer transport parameters into a fixed 1024-byte stack buffer     without bounds checking. When qlog was enabled, a remote attacker could possibly use this issue to execute     arbitrary code.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - ngtcp2 is a C implementation of the IETF QUIC protocol. In versions prior to 1.22.1,
    ngtcp2_qlog_parameters_set_transport_params() serializes peer transport parameters into a fixed 1024-byte
    stack buffer without bounds checking. When qlog is enabled, a remote peer can send sufficiently large
    transport parameters during the QUIC handshake to cause writes beyond the buffer boundary, resulting in a
    stack buffer overflow. This affects deployments that enable the qlog callback and process untrusted peer
    transport parameters. This issue has been fixed in version 1.22.1. If developers are unable to immediately
    upgrade, they can disable the qlog on client. (CVE-2026-40170)

It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-1633 advisory.
