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

  - A flaw was found in crun. When crun is built with libkrun and a container is started rootful with passt
    networking (krun.use_passt), crun can execute attacker-controlled payload from the container image with
    host root privileges. The issue is a regression in crun 1.29. It affects crun >= 1.29 (CVE-2026-84042)

  - A flaw was found in crun. When the container configuration does not give /dev a dedicated mount, terminal
    setup can redirect /dev/console onto an attacker-controlled path, including via the read-only-rootfs bind-
    mount fallback. Affected versions are crun 1.29.1 and earlier. Default configurations that mount a fresh
    /dev are not exposed. No fixed release is available yet. (CVE-2026-88264)

  - A flaw was found in crun. After pivot_root, reopening /dev/null for stdio can follow a symlink and attach
    a host file to container stdio, then change that file's ownership. Affected versions are crun 1.29.1 and
    earlier. Default configurations that mount a fresh /dev are not exposed. No fixed release is available
    yet. (CVE-2026-88265)

Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且廠商未提供可用的修補程式。

  - 在 crun 中發現缺陷。當使用 libkrun 構建 crun 並且容器使用 passt 網絡 （krun.use_passt） 啟動 rootful 時，crun 可以使用主機 root 權限從容器映像執行攻擊者控制的負載。問題是 crun 1.29的回歸。它會影響 crun >= 1.29 （CVE-2026-84042）

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 crun 中发现一个缺陷。当 crun 是以 libkrun 构建，并且容器是通过 passt networking （krun.use_passt） 来 rootful 启动时，crun 可能会使用主机 root 权限，从容器映像执行受攻击者控制的负载。此问题是 crun 1.29中的回归。这会影响 crun >= 1.29 （CVE-2026-84042）

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

Linux/Unix ホストには、ベンダーが提供するパッチが利用できない脆弱性の影響を受ける複数のパッケージがインストールされています。

  - crun に欠陥が見つかりました。crun が libkrun で構築され、コンテナが passt networking(krun.use_passt)で rootful に起動される場合、crun はホスト root 権限でコンテナイメージから攻撃者が制御するペイロードを実行できます。問題は crun 1.29 の回帰です。crun >= 1.29 に影響します(CVE-2026-84042)

Nessus は、ベンダーから報告されたパッケージの存在に依存していることに注意してください。
