Repro Steps

The Ubuntu 24.04 distro and a distro I build are getting the exact same network configurations. They have the same MAC address. And a "docker0" network which should not appear on the ubuntu distro since I never installed docker on that distro appeared.
Ubuntu:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1280 qdisc mq state UP group default qlen 1000
    link/ether 00:15:5d:a7:47:e7 brd ff:ff:ff:ff:ff:ff
    inet 172.27.141.183/20 brd 172.27.143.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fea7:47e7/64 scope link
       valid_lft forever preferred_lft forever
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    link/ether 02:42:03:3b:17:e8 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever

My distro:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host noprefixroute
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1280 qdisc mq qlen 1000
    link/ether 00:15:5d:a7:47:e7 brd ff:ff:ff:ff:ff:ff
    inet 172.27.141.183/20 brd 172.27.143.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::215:5dff:fea7:47e7/64 scope link
       valid_lft forever preferred_lft forever
3: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
    link/ether 02:42:03:3b:17:e8 brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever

Both distros' networking are not working at this moment.

Expected Behavior

The network should be isolated between the two distros and work properly for both. (Or at least the Ubuntu one if there is something wrong with my distro.)

Actual Behavior

The distros' networks are somehow tangled together.

I just found out that WSL share a network namespace across all "distros".
Still, no idea why the network do not work.
