"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-107315 advisory.

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

    HID: multitouch: Add NULL check in mt_input_configured

    devm_kasprintf() can return a NULL pointer on failure,but this
    returned value in mt_input_configured() is not checked.
    Add NULL check in mt_input_configured(), to handle kernel NULL
    pointer dereference error.

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.");
