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.

It's a privilege escalation.

The vulnerability, tracked as CVE-2024-1086 and carrying a severity rating of 7.8 out of a possible 10, allows people who have already gained a foothold inside an affected system to escalate their system privileges. It’s the result of a use-after-free error, a class of vulnerability that occurs in software written in the C and C++ languages when a process continues to access a memory location after it has been freed or deallocated. Use-after-free vulnerabilities can result in remote code or privilege escalation.

Immediately I noticed how when Teslas can't drive themselves we also blame the car and not the driver.

Weak. Blame the driver.

I compiled my own drivers

This guy drives not

And then compacted them!

Yeah, but did you include any biobs?

I re-wrote my Tesla firmware in Rust. It is faster and more secure. Self-driving is no problem when you use a safe language.

Honestly, why are we even selling cars to people who do not take these basic steps?

Don't think C / C++ wasn't blamed.

This is why least privilege is so important. If one account is compromised it will be harder to compromise others if the original account is isolated.
