Device: xiaomi 9se
Android version: 11
Magisk version name: v25.2
Magisk version code: 25201

I previously found a library on github that can get mac addresses via netlink, but after Android 11, this method doesn't work due to selinux limitations (log: avc nlmsg_readpriv denied, class netlink_route_socket). After flashing magisk boot, this method takes effect again and will not report avc denied.

I have studied magisk for a long time and have not found out what causes it. Does anyone know what causes it?

the library:
