CVE-2026-28904 (opens in a new tab)How to fix?
Upgrade wpe_webkit to version 2.52.4 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Overflow in the process of handling web content. An attacker can cause a process crash or potentially execute arbitrary code by tricking a user into processing or loading specially crafted 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 avoiding the processing or loading of untrusted web content and, where feasible, removing unnecessary packages that require the affected component. Removing WebKitGTK3 is also suggested if not required, as it does not impact system functionality.
