The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013248 advisory.

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

    scsi: message: mptlan: Fix use after free bug in mptlan_remove() due to race condition

    mptlan_probe() calls mpt_register_lan_device() which initializes the     &priv->post_buckets_task workqueue. A call to     mpt_lan_wake_post_buckets_task() will subsequently start the work.

    During driver unload in mptlan_remove() the following race may occur:

    CPU0                  CPU1

                        |mpt_lan_post_receive_buckets_work()     mptlan_remove()     |       free_netdev()     |         kfree(dev);     |                         |                         | dev->mtu                         |   //use

    Fix this by finishing the work prior to cleaning up in mptlan_remove().

    [mkp: we really should remove mptlan instead of attempting to fix it]

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.

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

  - scsi: message: mptlan: Fix use after free bug in mptlan_remove() due to race condition mptlan_probe()     calls mpt_register_lan_device() which initializes the &priv->post_buckets_task workqueue.

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

An update of the linux package has been released.
