The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-988808 advisory.

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

    usb: gadget: f_fs: Prevent race during ffs_ep0_queue_wait

    While performing fast composition switch, there is a possibility that the     process of ffs_ep0_write/ffs_ep0_read get into a race condition     due to ep0req being freed up from functionfs_unbind.

    Consider the scenario that the ffs_ep0_write calls the ffs_ep0_queue_wait     by taking a lock &ffs->ev.waitq.lock. However, the functionfs_unbind isn't     bounded so it can go ahead and mark the ep0req to NULL, and since there     is no NULL check in ffs_ep0_queue_wait we will end up in use-after-free.

    Fix this by making a serialized execution between the two functions using     a mutex_lock(ffs->mutex).

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.
