What’s new in security for Ubuntu 26.10?

Ubuntu 26.10 “Stonking Stingray” arrives at a time when AI tools are accelerating vulnerability discovery. Patching faster is essential, but the resilience of the underlying operating system must also limit what an attacker can achieve before a fix is available. To respond to this new threat landscape, Ubuntu 26.10 continues the work of previous releases by reducing the code exposed to attack: replacing memory-unsafe implementations while preserving confinement as components change.
