Red Hat rates this Important.
Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory.
To reduce exposure to this vulnerability, apply operational controls and ensure sandboxing is maintained:
1. Avoid visiting untrusted websites or following untrusted links that could render malicious HTML and graphics content.
2. Ensure that Chromium's built-in multi-process sandbox remains enabled. Do not run the browser with sandbox-disabling options such as the `--no-sandbox` command-line flag.
3. If the browser is not required on the system, remove the package:
# dnf remove chromium-browser
Caveats: Restricting web browsing or removing the browser package will affect user workflows that depend on web access. Operational controls such as avoiding untrusted content do not eliminate risk from compromised trusted sites.
