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。

  - irqchip/irq-mvebu-gicp修正 mvebu_gicp_probe 中的 refcount 洩漏 of_irq_find_parent() 傳回節點指標時 refcount 已遞增。我們應該在不再需要時對其使用 of_node_put()。新增遺漏的 of_node_put() 以避免 refcount 洩漏。 (CVE-2023-53757)

請注意，Nessus 依賴供應商報告的套件存在。

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。

  - irqchip/irq-mvebu-gicp修复 mvebu_gicp_probe 中的 refcount 泄漏of_irq_find_parent() 返回 refcount 增加的节点指针不再需要时应使用 of_node_put()。添加缺少的 of_node_put() 以避免 refcount 泄漏。 (CVE-2023-53757)

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。

  - irqchip/irq-mvebu-gicp: mvebu_gicp_probe での refcount 漏洩を修正します。of_irq_find_parent() は、refcount が増加されたノードポインターを返します。現時点で必要のない場合は、これ上で of_node_put() を使用する必要があります。refcount の漏洩を回避するために欠落している of_node_put() を追加します。CVE-2023-53757

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。

An update of the linux package has been released.

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

  - irqchip/irq-mvebu-gicp: Fix refcount leak in mvebu_gicp_probe of_irq_find_parent() returns a node pointer     with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing     of_node_put() to avoid refcount leak. (CVE-2023-53757)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007490 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    irqchip/irq-mvebu-gicp: Fix refcount leak in mvebu_gicp_probe

    of_irq_find_parent() returns a node pointer with refcount incremented,     We should use of_node_put() on it when not needed anymore.
    Add missing of_node_put() to avoid refcount leak.

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

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