The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-992540 advisory.

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

    media: dvbdev: adopts refcnt to avoid UAF

    dvb_unregister_device() is known that prone to use-after-free.
    That is, the cleanup from dvb_unregister_device() releases the dvb_device     even if there are pointers stored in file->private_data still refer to it.

    This patch adds a reference counter into struct dvb_device and delays its     deallocation until no pointer refers to the object.

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.
