There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious
    user can use scripting commands to inject arbitrary information into the response stream for the given
    client, potentially corrupting or returning tampered data to other users on the same connection. The error
    handling code for lua scripts does not properly handle null characters. Versions 9.0.2, 8.1.6, 8.0.7, and
    7.2.12 fix the issue. (CVE-2025-67733)

  - Valkey is a distributed key-value database. Prior to versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12, a malicious
    actor with access to the Valkey clusterbus port can send an invalid packet that may cause an out bound
    read, which might result in the system crashing. The Valkey clusterbus packet processing code does not
    validate that a clusterbus ping extension packet is located within buffer of the clusterbus packet before
    attempting to read it. Versions 9.0.2, 8.1.6, 8.0.7, and 7.2.12 fix the issue. As an additional
    mitigation, don't expose the cluster bus connection directly to end users, and protect the connection with
    its own network ACLs. (CVE-2026-21863)

  - Valkey is a distributed key-value database. Starting in version 9.0.0 and prior to version 9.0.3, a
    malicious actor with network access to Valkey can cause the system to abort by triggering an assertion.
    When processing incoming requests, the Valkey system does not properly reset the networking state after
    processing an empty request. A malicious actor can then send a request that the server incorrectly
    identifies as breaking server side invariants, which results in the server shutting down. Version 9.0.3
    fixes the issue. As an additional mitigation, properly isolate Valkey deployments so that only trusted
    users have access. (CVE-2026-27623)

リモートの Fedora 44 ホストには、 FEDORA-2026-ca1077dd2e アドバイザリに記載された複数の脆弱性の影響を受けるパッケージがインストールされています。

Tenable は、前述の記述ブロックを Fedora セキュリティアドバイザリから直接抽出しています。

Nessus はこれらの問題をテストしておらず、代わりにアプリケーションが自己報告するバージョン番号にのみ依存していることに注意してください。

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-ca1077dd2e advisory.
