Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-08 15:31

Details

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.

Severity ?

8.8 (High)
