As no clear cause found, add rules ahead for RTL8922DE\nto avoid crash if it happens.", "A flaw was found in the Linux kernel's `rtw89` WiFi driver. This vulnerability arises from insufficient validation of release report content, specifically affecting the `RTL8922DE` chip. If a malformed release report is processed, it can lead to a system crash, resulting in a Denial of Service (DoS)." ],
