CVE-2026-113053
Description
A flaw was found in chromium-browser. This flaw allows a remote attacker to execute arbitrary code within the browser sandbox by enticing a user to visit a specially crafted HTML page. The vulnerability is caused by a use-after-free memory error during cookie handling.
Statement
This vulnerability is rated as Important because an unauthenticated remote attacker can achieve arbitrary code execution inside the renderer sandbox if a user visits a malicious website. Although this permits code execution without prior privileges, the severity is categorized as Important rather than Critical because the browser multi-process sandbox restricts the blast radius, preventing direct compromise of the host system without an additional privilege escalation flaw. Furthermore, the chromium package is not included in Red Hat Enterprise Linux and is maintained only in community repositories such as Fedora and EPEL.
