Linux is everywhere! This also shows that Debian Linux is very stable for
it to be used in a commercial network device.

UniFi Cloud Key Gen 2 Plus is powered by Debian Linux 9

Please note that Debian 9 (stretch) is no longer security supported by
Debian, so you may want to upgrade your devices to a newer release.

In addition there are at least two third-party organisations providing
extended support for older versions of Debian.

Linux Teo-En-Ming-Corporation 3.18.44-ui-qcom #1 SMP Mon Aug 1
14:33:30 CST 2022 aarch64 GNU/Linux

I note that this is a very old version of the Linux kernel that is no
longer supported by the Linux kernel community and so it may have some
vulnerabilities in it, including remote ones.

https://www.kernel.org/

I note that the version string indicates that this is a fork of the
Linux kernel, please consider asking the company providing the device
to get involved in the upstream community and submitting their changes
for inclusion in the official Linux version.
