"The remote AlmaLinux 9 host has packages installed that are affected by a vulnerability as referenced in the
ALSA-2023:3715 advisory.

  - A vulnerability was found in libvirt. This security flaw ouccers due to repeatedly querying an SR-IOV PCI
    device's capabilities that exposes a memory leak caused by a failure to free the virPCIVirtualFunction
    array within the parent struct's g_autoptr cleanup. (CVE-2023-2700)
