Ubuntu 25.10 Introduces sudo-rs: Rust-Based sudo Replacement
Hot Ubuntu Updates: Ubuntu 25.10 Introduces sudo-rs. Ubuntu is making a great change in its upcoming 25.10 release by adopting sudo-rs as the default, which is a Rust-based reimplementation of the traditional sudo command. This change plans to increase the system security and reliability by forcing Rust’s memory safety features. Proceed to the rest of the article from the Orcacore website to discover more information about memory-safe sudo to become the default in Ubuntu.

Ubuntu 25.10 Introduces sudo-rs: A Safer sudo Replacement in Rust
For years, the sudo command has been a main option in Linux systems, which allows users to perform their administrative tasks. But because it is written in the C programming language, it makes it vulnerable, especially in memory management. This new sudo replacement, which is called sudo-rs (Memory-safe sudo), is written in Rust, a programming language known for safety and performance.
Ubuntu plans to reduce the risk of memory-related security issues and provide a more secure environment for users by adopting sudo-rs.
Why Rust-based sudo?
Rust is designed to prevent common programming errors that can lead to security vulnerabilities, such as buffer overflows and null pointer dereferencing. Its strong safety guarantees make it an ideal choice for system-level programming.
By transitioning to Rust-based utilities like sudo-rs, Ubuntu is taking proactive steps to enhance the overall security and stability of its operating system.
What Does sudo-rs Mean for Ubuntu Users?
For most users, the switch to sudo-rs will be simple. The new implementation is designed to be compatible with existing workflows, so you can continue using sudo as you always have. Behind the scenes, however, you’ll benefit from the improved safety and reliability that Rust brings to the table.
Ubuntu 25.10: The Test for sudo-rs
Before Ubuntu makes sudo-rs the default in the next Long Term Support release (Ubuntu 26.04), it is testing it out first in Ubuntu 25.10. Also, Ubuntu helps the developers to imporve sudo-rs. Here are the specific things Ubuntu is going to add:
- Better security for running shell commands: This makes it harder for hackers to escape restrictions and get control of the system.
- Support for AppArmor: This is Ubuntu’s built-in security system, and they want sudo-rs to work with it smoothly.
- A feature called sudoedit: This lets users safely edit files with admin rights without giving full control.
- Support for older Linux kernels: Even though sudo-rs is new, it still needs to work on older systems. For example, Ubuntu 20.04 is still widely used, and they don’t want things to break if you’re using containers between different versions.
Even though it might seem strange to support older systems, it’s really important. Without it, running a newer Ubuntu container on an older host could cause sudo to stop working, and that would be a big problem.
Ubuntu’s also making sure all the tests for sudo-rs work properly on their system. This way, they can catch and fix any issues early on.
Final Words
This isn’t just about replacing one program with another. It’s about showing that Ubuntu is serious about long-term security and building a system that lasts. They’re not throwing away C programming or rewriting everything in Rust, but by choosing to update such an important tool, they’re showing that the future needs to be safer, stronger, and more reliable.
