"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-382934 advisory.

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

    wifi: ar5523: enable proper endpoint verification

    Syzkaller reports [1] hitting a warning about an endpoint in use
    not having an expected type to it.

    Fix the issue by checking for the existence of all proper
    endpoints with their according types intact.

    Sadly, this patch has not been tested on real hardware.

    [1] Syzkaller report:
