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。

  - NFSD在 /proc/fs/nfs/exports fd 的生命周期内保持网络引用 /proc/fs/nfs/exports proc 条目在模块 init 中创建并在模块的生命周期内持续存在。 exports_proc_open() 捕获调用程序的当前网络命名空间并将其 svc_export_cache 存储在 seq->private 中但未采用任何对该命名空间的引用。如果命名空间随后被拆除例如在 opener 对不同的命名空间执行 setns() 之后容器遭到破坏nfsd_net_exit() 会调用会释放缓存的 nfsd_export_shutdown()。对仍然打开的 fd 的后续读取会取消引用已释放的 cache_detail从而遍历已释放的哈希表。在打开文件描述符的生命周期中保持 struct net 上的引用。当任何导出 fd 打开时这会阻止 nfsd_net_exit() 运行从而阻止 nfsd_export_shutdown() 释放缓存。 cache_detail 已存储其 net 指针cd->net, 由 cache_create_net() 设置因此 exports_release() 无需额外的每个文件存储即可检索该指针。 (CVE-2026-31403)

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 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - NFSD在 /proc/fs/nfs/exports fd 的存留期保留網路參照。/proc/fs/nfs/exports proc 項目是在模組初始化時建立並在模組的存留期持續存在。 exports_proc_open() 會擷取呼叫者目前的網路命名空間並將其 svc_export_cache 儲存在 seq->private 中但不會參照命名空間。如果隨後移除命名空間 (例如在 opener 對不同的命名空間執行 setns() 之後容器損毀)nfsd_net_exit() 會呼叫 nfsd_export_shutdown()其可釋放快取。在仍處於開啟狀態的 fd 上後續讀取會對已釋放的 cache_detail 執行遍歷已釋放的雜湊表。針對開啟檔案描述符號的存留期保留 struct net 上的參照。這可防止 nfsd_net_exit() 在任何匯出 fd 開啟時執行 -- 進而防止 nfsd_export_shutdown() 釋出快取。 cache_detail 已儲存其網路指標 (cd->net由 cache_create_net() 設定)因此 exports_release() 可擷取該指標而無需每個檔案的額外儲存空間。 (CVE-2026-31403)

請注意，Nessus 的判定取決於廠商所報告的套件是否存在。

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。

  - NFSD/proc/fs/nfs/exports fd の有効期間の間、ネット参照を保持します。/proc/fs/nfs/exports proc エントリは、モジュール init で作成され、モジュールの有効期間の間、保持します。 exports_proc_open() は、呼び出し元の現在のネットワーク名前空間をキャプチャして、その svc_export_cache を seq->private に保存しますが、名前空間を参照しません。名前空間がその後にダウングレードされた場合例opener が異なる名前空間に setns() を設定した後のコンテナ破壊など、nfsd_net_exit() はキャッシュを解放する nfsd_export_shutdown() を呼び出します。まだ開いている fd でのその後の読み取りで、解放された cache_detail が逆参照され、解放されたハッシュテーブルをウォークします。開いているファイル記述子の有効期間の間、struct net 上の参照を保留します。これは nfsd_net_exit() が実行されないようにし、したがってエクスポート fd が開いているときに nfsd_export_shutdown() がキャッシュを解放することも防止します。 cache_detail がすでにネットポインターを保存しているので (cd->net、cache_create_net() によって設定されている)、exports_release() はファイルごとの追加ストレージなしでそれを取得できます。CVE-2026-31403

Nessus は、ベンダーによって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。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - NFSD: Hold net reference for the lifetime of /proc/fs/nfs/exports fd The /proc/fs/nfs/exports proc entry     is created at module init and persists for the module's lifetime. exports_proc_open() captures the     caller's current network namespace and stores its svc_export_cache in seq->private, but takes no reference     on the namespace. If the namespace is subsequently torn down (e.g. container destruction after the opener     does setns() to a different namespace), nfsd_net_exit() calls nfsd_export_shutdown() which frees the     cache. Subsequent reads on the still-open fd dereference the freed cache_detail, walking a freed hash     table. Hold a reference on the struct net for the lifetime of the open file descriptor. This prevents     nfsd_net_exit() from running -- and thus prevents nfsd_export_shutdown() from freeing the cache -- while     any exports fd is open. cache_detail already stores its net pointer (cd->net, set by cache_create_net()),     so exports_release() can retrieve it without additional per-file storage. (CVE-2026-31403)

Note that Nessus relies on the presence of the package as reported by the vendor.

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.85-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

    Further information about Debian Security Advisories, how to apply     these updates to your system and frequently asked questions can be     found at: https://www.debian.org/security/

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1596 advisory.
