CVE-2026-20635 (opens in a new tab)How to fix?
Upgrade webkitgtk to version 2.50.6 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Overflow via the memory handling process. An attacker can cause an unexpected process crash or potentially execute arbitrary code by tricking a user into processing or loading malicious web content. This is only exploitable if the system has specific packages installed and is being used via a graphical interface to process untrusted web content, such as through GNOME. In certain configurations, exploitation may be possible from the local network without user interaction.
Workaround
This vulnerability can be mitigated by not processing or loading untrusted web content, or by removing the dependent packages that require the vulnerable component. Removing WebKitGTK3 is also suggested, as it is not required by any package and can be removed without breaking functionality.
