Red Hat
Red Hat rates this Important.
Red Hat rates this vulnerability as Important because a sandbox breakout capable of arbitrary host execution presents a severe blast radius. However, exploitation requires notable prerequisites, as an attacker must already control the renderer process through a separate exploit and persuade a victim to navigate to a malicious web page. Furthermore, upstream advisories indicate that this flaw is restricted to the Windows platform, presenting no direct risk to Red Hat Enterprise Linux.
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.
