Drive encryption wouldn't do anything to mitigate this though? A process running on your PC needs access to your drive, and so with the current setup you have either the option to trust 100% every software with your signal encryption keys, or to simply not use them.

Seems like a pretty big security flaw that we have actual solutions to.

You could maybe form a hackey way to allow only the signal process to an encrypted FUSE filesystem that decrypts its own keys on the fly, but again there's already ways to do this in software that isn't like using a wrench to plug a leak. (and this setup would just have it's own set of keys that need to be protected now, probably by a traditional method like kwallet)

I mean... Every serious operating system already has some form of keyring feature right?

Ie. what signal should be using, yet isnt

there is SELinux which give more fine tuned permissions for each app but it was too complicated for me

And if you're using SELinux as a kwallet/keyring replacement, you're using it wrong (but again security in layers doesn't stop you from using both)
