This leads to 2 use-after-free issues: 1. New watchdog devices registered after this point will inherit the dangling `default_gov`. 2. Existing watchdog devices using the unregistered governor will have their `wdd-&gt;gov` reassigned to the dangling `default_gov`.</p> <p>Fix the UAF by clearing `default_gov` if it matches the governor being unregistered.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>watchdog: pretimeout: Fix UAF in watchdog_unregister_governor()</p> <p>When a watchdog governor is unregistered, it updates existing watchdog devices that were using this governor by falling back to `default_gov`.</p> <p>If the governor being unregistered is currently set as `default_gov`, the `default_gov` is never cleared.
