Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: pci: validate release report content before using for RTL8922DE
The commit 957eda596c76
("wifi: rtw89: pci: validate sequence number of TX release report")
does validation on existing chips, which somehow a release report of SKB
becomes malformed. As no clear cause found, add rules ahead for RTL8922DE
to avoid crash if it happens.
