"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-989767 advisory.

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

    net: atlantic: remove aq_nic_deinit() when resume

    aq_nic_deinit() has been called while suspending, so we don't have to call
    it again on resume.
    Actually, call it again leads to another hang issue when resuming from
    S3.
