There are no vulnerabilities in Linux, not a single one.
I code, princess. All software has bugs/vulnerabilities. Saying Linux is perfectly secure is insane. Even the Qubes OS and Tails OS distros are not perfect. You go ahead and trust MS to fix all the b/v in Windows while I will much prefer the open approach. I hope no one steals your tiara when another 0 day for Windows opens your drawers after MS is scrambling to fix it and hackers are exploiting it. I prefer the Linux army of coders to address issues to MS’s squad of coders in sheer numbers of emergency responders. Want to know how long 0 days stay open on Linux? 0 days. Hell, half (more than) of the black hat hackers run Linux and don’t want to run a vulnerable OS.
Just a hint. If someone running Kali Linux moves into the neighborhood forget about having any security if you are not running EVERYTHING through a VPN or run cables to everything.
