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。

  - 已解決 Linux 核心中的下列弱點：net: dsa: mxl862xx: fix use-after-free of DSA ports in crc_err_work Upon an MDIO CRC error mxl862xx_crc_err_work_fn() walks the DSA ports and closes the CPU port conduits: dsa_switch_for_each_cpu_port(dp, priv->ds) dev_close(dp->conduit);
    mxl862xx_remove() unregisters the switch before cancelling this work: set_bit(MXL862XX_FLAG_WORK_STOPPED, &priv->flags); cancel_delayed_work_sync(&priv->stats_work); dsa_unregister_switch(ds);
    mxl862xx_host_shutdown(priv); dsa_unregister_switch() frees the dsa_port objects. If a CRC error schedules the work during teardown it can run after the ports have been freed and dereference freed memory. Guard the port walk with MXL862XX_FLAG_WORK_STOPPED, which is already set before dsa_unregister_switch(). DSA tears the ports down under rtnl_lock(), so checking the flag under rtnl_lock() means the work either runs before teardown and sees valid ports, or runs afterwards, observes the flag and skips the walk. This mirrors the host_flood_work handler, which skips torn-down ports under rtnl_lock(). (CVE-2026-72411)

請注意，Nessus 依賴供應商報告的套件存在。

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.

  - In the Linux kernel, the following vulnerability has been resolved: net: dsa: mxl862xx: fix use-after-free     of DSA ports in crc_err_work Upon an MDIO CRC error mxl862xx_crc_err_work_fn() walks the DSA ports and     closes the CPU port conduits: dsa_switch_for_each_cpu_port(dp, priv->ds) dev_close(dp->conduit);
    mxl862xx_remove() unregisters the switch before cancelling this work: set_bit(MXL862XX_FLAG_WORK_STOPPED,     &priv->flags); cancel_delayed_work_sync(&priv->stats_work); dsa_unregister_switch(ds);
    mxl862xx_host_shutdown(priv); dsa_unregister_switch() frees the dsa_port objects. If a CRC error schedules     the work during teardown it can run after the ports have been freed and dereference freed memory. Guard     the port walk with MXL862XX_FLAG_WORK_STOPPED, which is already set before dsa_unregister_switch(). DSA     tears the ports down under rtnl_lock(), so checking the flag under rtnl_lock() means the work either runs     before teardown and sees valid ports, or runs afterwards, observes the flag and skips the walk. This     mirrors the host_flood_work handler, which skips torn-down ports under rtnl_lock(). (CVE-2026-72411)

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