"The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore,
affected by a vulnerability as referenced in the CVE-2024-58071 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: team: prevent adding a device which is
    already a team device lower Prevent adding a device which is already a team device lower, e.g. adding
    veth0 if vlan1 was already added and veth0 is a lower of vlan1. This is not useful in practice and can
    lead to recursive locking: $ ip link add veth0 type veth peer name veth1 $ ip link set veth0 up $ ip link
    set veth1 up $ ip link add link veth0 name veth0.1 type vlan protocol 802.1Q id 1 $ ip link add team0 type
    team $ ip link set veth0.1 down $ ip link set veth0.1 master team0 team0: Port device veth0.1 added $ ip
    link set veth0 down $ ip link set veth0 master team0 ============================================ WARNING:
