Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory.
Avoid accessing untrusted websites or processing untrusted HTML content within Chromium. Ensure that built-in browser sandboxing mechanisms remain active and are not bypassed.
If Chromium is not required on the system, remove the package to eliminate exposure:
# dnf remove chromium-browser
Caveats: Removing the chromium-browser package will make the browser unavailable and may affect user desktop environments or workflows that depend on it for web rendering.
