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

  - In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_ecm: Fix net_device
    lifecycle with device_move The net_device is allocated during function instance creation and registered
    during the bind phase with the gadget device as its sysfs parent. When the function unbinds, the parent
    device is destroyed, but the net_device survives, resulting in dangling sysfs symlinks: console:/ # ls -l
    /sys/class/net/usb0 lrwxrwxrwx ... /sys/class/net/usb0 -> /sys/devices/platform/.../gadget.0/net/usb0
    console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0 ls: .../gadget.0/net/usb0: No such file or
    directory Use device_move() to reparent the net_device between the gadget device tree and
    /sys/devices/virtual across bind and unbind cycles. During the final unbind, calling device_move(NULL)
    moves the net_device to the virtual device tree before the gadget device is destroyed. On rebinding,
    device_move() reparents the device back under the new gadget, ensuring proper sysfs topology and power
    management ordering. To maintain compatibility with legacy composite drivers (e.g., multi.c), the bound
    flag is used to indicate whether the network device is shared and pre-registered during the legacy
    driver's bind phase. (CVE-2026-31725)

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。

  - USB： gadget： f_ecm：修正net_device生命週期 具有 device_move net_device 會在函式執行個體建立期間配置，並在繫結階段註冊，並將小工具裝置作為其 sysfs 父項。當函式解除綁定時，父裝置會被破壞，但net_device仍然存在，導致懸空的 sysfs 符號連結： console：/ # ls -l /sys/class/net/usb0 lrwxrwxrwx ... /sys/class/net/usb0 -> /sys/devices/platform/.../gadget.0/net/usb0 console：/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0 ls： .../gadget.0/net/usb0： 沒有這樣的檔案或目錄 使用 device_move（） net_device跨綁定和取消綁定循環。在最後解除綁定期間，呼叫 device_move （NULL） 會在小工具裝置遭到破壞之前，將net_device移至虛擬裝置樹狀結構。重新綁定時，device_move（） 會將裝置重新父系到新小工具下，確保正確的 sysfs 拓撲和電源管理順序。為了維持與舊版複合驅動程式 （例如 multi.c） 的相容性，繫結旗標可用來指出在舊版驅動程式的繫結階段期間，是否共用和預先註冊網路裝置。（CVE-2026-31725）

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。

  - usb：gadget：f_ecm：修复device_move net_device生命周期 net_device在函数实例创建期间分配，并在绑定阶段使用小工具设备作为其 sysfs 父项进行注册。函数取消绑定时，父设备会损坏，但net_device仍然存活，从而导致悬摆 sysfs 符号链接： console：/ # ls -l /sys/class/net/usb0 lrwxrwxrwx ... /sys/class/net/usb0 -> /sys/devices/platform/.../gadget.0/net/usb0 console：/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0 ls： .../gadget.0/net/usb0： 没有此类文件或目录 使用 device_move（net_device） 跨绑定和取消绑定周期。在最终取消绑定期间，调用 device_move（NULL） 会在小工具设备销毁之前，将net_device移动到虚拟设备树。重新绑定时，device_move（） 将设备重命名为新小工具下的父项，从而确保 sysfs 拓扑结构和电源管理顺序正确。为了保持与旧版复合驱动程序（例如 multi.c）的兼容性，绑定标记用于指示在旧版驱动程序的绑定阶段是否共享和预注册网络设备。（CVE-2026-31725）

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。

  - usb:gadget: f_ecm:device_move でのnet_deviceのライフサイクルを修正します net_deviceは関数インスタンスの作成中に割り当てられ、バインドフェーズ中に sysfs 親としてガジェットデバイスとして登録されます。関数がバインド解除されると、親デバイスは破壊されますが、net_deviceは生き残り、ダングリング sysfs シンボリックリンクが発生します: console:/ # ls -l /sys/class/net/usb0 lrwxrwxrwx ... /sys/class/net/usb0 -> /sys/devices/platform/.../gadget.0/net/usb0 console:/ # ls -l /sys/devices/platform/.../gadget.0/net/usb0 ls: .../gadget.0/net/usb0: 該当するファイルまたはディレクトリがありません device_move() を使用して、ガジェットデバイスツリーと /sys/devices/virtual の間のnet_deviceを bind とバインド解除サイクル。最後のバインド解除中に、device_move(NULL)を呼び出すと、ガジェットデバイスが破棄される前に、net_deviceが仮想デバイスツリーに移動します。再バインド時に、device_move()は新しいガジェットの下でデバイスを再親子として戻し、適切なsysfsトポロジーと電源管理の順序を確保します。レガシーコンポジットドライバー(multi.cなど)との互換性を維持するために、レガシードライバーのバインドフェーズ中にネットワークデバイスが共有され、事前登録されているかどうかを示すためにバインドフラグが使用されます。(CVE-2026-31725)
