Description

ChromeOS is a lightweight operating system developed by Google for Chromebooks, optimized for secure web browsing and cloud-based computing. ChromeOS Flex extends this operating system to older PCs and Macs.

Multiple vulnerabilities exist in Google ChromeOS due to improper input validation, memory corruption, and insufficient security checks within system components and the underlying Chromium browser engine. An attacker could exploit these vulnerabilities by persuading a victim to visit a specially crafted web page.

Successful exploitation may result in arbitrary code execution, privilege escalation, disclosure of sensitive information, or denial-of-service conditions on the affected system.
