An update of the linux package has been released.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007500 advisory.

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

    usb: gadget: f_hid: fix f_hidg lifetime vs cdev

    The embedded struct cdev does not have its lifetime correctly tied to     the enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN     is held open while the gadget is deleted.

    This can readily be replicated with libusbgx's example programs (for     conciseness - operating directly via configfs is equivalent):

            gadget-hid             exec 3<> /dev/hidg0             gadget-vid-pid-remove             exec 3<&-

    Pull the existing device up in to struct f_hidg and make use of the     cdev_device_{add,del}() helpers.  This changes the lifetime of the     device object to match struct f_hidg, but note that it is still added     and deleted at the same time.

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.

  - usb: gadget: f_hid: fix f_hidg lifetime vs cdev The embedded struct cdev does not have its lifetime     correctly tied to the enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN is held open     while the gadget is deleted. This can readily be replicated with libusbgx's example programs (for     conciseness - operating directly via configfs is equivalent): gadget-hid exec 3<> /dev/hidg0 gadget-vid-     pid-remove exec 3<&- Pull the existing device up in to struct f_hidg and make use of the     cdev_device_{add,del}() helpers. This changes the lifetime of the device object to match struct f_hidg,     but note that it is still added and deleted at the same time. (CVE-2022-50568)

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