True, but that doesn't necessarily matter if I can compromise the privileged app instead. I could replace it, modify it on disk, or really any number of things in order to get myself a hook into a privileged position.

Just injecting code in some function call which launches malware.exe would do the trick. Ofc signature checks and the like can help here - but those aren't a given. There's any number of ways you can elevate yourself on a system based off of user security if your threat model is malicious processes. Linux (and windows) will stop users from accessing each other's crap by default, but not processes.

Or: supply chain attacks. Now your official app without any modifications is malicious.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
