Red Hat
Red Hat rates this Important.
This vulnerability is rated as Important because an attacker can break process isolation boundaries to access memory outside the restricted environment, resulting in significant confidentiality impact. In Red Hat Enterprise Linux workstation and desktop environments running Chromium, the browser relies on sandboxing to isolate untrusted web content. Although exploitation requires convincing a user to view a malicious page and presumes prior compromise of the renderer subsystem, crossing sandbox barriers to disclose host memory warrants an elevated severity.
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
