This vulnerability was reported on **April 29, 2026**. It represents one of the most extensive Linux kernel vulnerabilities in recent years, with a potential impact on the entire global Linux fleet. Our security team became aware of this disclosure the same day it was published and immediately initiated the necessary investigations. This flaw, located in the kernel's cryptographic subsystem (via the `AF_ALG` interface), allows for **Local Privilege Escalation (LPE)**. - On a standard server, it allows a standard user to become `root` (administrator). - In a containerized environment (such as **Docker** or **Kubernetes**), it allows for a container escape to take control of the host node.
