Linux

Linux is the widely-used open-source operating system kernel found across servers, desktops, and embedded systems worldwide. This high-severity vulnerability requires local access with user-level privileges and can be exploited without user interaction, potentially allowing an attacker to compromise system confidentiality, integrity, and availability across multiple security domains. Security teams should monitor for patches released by Linux distributions before the October 15, 2025 deadline and prioritize testing and deployment for systems where local user access is possible.
