"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-383411 advisory.

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

    HID: wacom: fix when get product name maybe null pointer

    Due to incorrect dev->product reporting by certain devices, null
    pointer dereferences occur when dev->product is empty, leading to
    potential system crashes.

    This issue was found on EXCELSIOR DL37-D05 device with
    Loongson-LS3A6000-7A2000-DL37 motherboard.
