CVE-2026-113279
Description
A flaw was found in chromium-browser. This vulnerability allows a remote attacker to achieve arbitrary code execution within the browser's restricted sandbox environment. By enticing a user to visit a specially crafted HTML page, an attacker can trigger memory corruption in the browser's Accessibility component.
Statement
This vulnerability is evaluated as Important rather than Critical because exploitation requires user interaction to navigate to a malicious web page, and any code execution is constrained within the browser sandbox environment. A secondary vulnerability would be required to escape sandbox restrictions and affect the underlying host operating system. Furthermore, Chromium is not shipped as part of core Red Hat Enterprise Linux and is only distributed through community channels such as Fedora and EPEL, significantly limiting exposure across enterprise environments.
