Red Hat
Red Hat rates this Important.
Red Hat Product Security rates the severity of this flaw as determined by the Google Chrome Security Advisory.
Advise users to avoid accessing untrusted websites, opening unverified links, or processing untrusted HTML media content. Ensure that Chromium's built-in multi-process sandbox remains active; do not launch the browser with sandbox-disabling options such as `--no-sandbox`.
On systems where desktop web browsing is not required (such as headless servers or environments where alternative browsers are standard), exposure can be eliminated by removing the optional browser package:
# dnf remove chromium-browser
Caveats: Removing the package removes the Chromium browser from the system and will disrupt local web browsing workflows and any dependent desktop applications. Ensure that administrative tools or user workflows do not depend on this package prior to removal.
