CVE-2026-113208
Description
A flaw was found in the ContextualSearch component of Chromium. A remote attacker could exploit this use-after-free vulnerability by convincing a user to visit a specially crafted HTML page. Successful exploitation allows the attacker to execute arbitrary code inside the browser sandbox.
Statement
Red Hat rates this vulnerability as Important because an unauthenticated remote attacker could compromise the client session by executing code within the browser sandbox upon tricking a user into rendering malicious web content. Although sandbox restrictions contain the blast radius and prevent direct host compromise, the potential for arbitrary code execution within the process elevates the severity above Moderate. Furthermore, Chromium is not shipped in core Red Hat Enterprise Linux repositories and is only available through community channels like EPEL, leaving standard enterprise installations unaffected.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
