[-- Attachment #1.1: Type: text/plain, Size: 38586 bytes --]

Dear RT2X00 driver maintainers,

We have discovered a critical vulnerability in the RT2X00 driver. We
recommend urgently submitting an update.

*Vulnerability Description*: When a PC is running Ubuntu 22.04 or 24.04,
executing our proof of concept (POC) can directly cause a null pointer
dereference or use-after-free (UAF). The systems we tested were:

- *Description*: Ubuntu 22.04.4 LTS *Release*: 22.04
- *Description*: Ubuntu 24.04 LTS *Release*: 24.04

We tested network cards from the RT2870/RT3070/RT5370 series, which all
belong to the RT2X00 driver group, and all were able to trigger the
vulnerability. Additionally, executing the POC requires only user-level
privileges. Debian systems are not affected.

Now, there are a few issues that need to be discussed. When executing the
POC on different PCs, it not only triggers a null pointer dereference but
also occasionally triggers a use-after-free (UAF) issue. You can test this
issue yourselves.

*POC Execution Method*:

python3 poc.py

Some systems might be affected by the time.sleep function. If you cannot
successfully reproduce the issue, please modify time.sleep(0.1) in the
script to time.sleep(0.2). Below, I will provide the logs of the null
pointer dereference and UAF from our kernel for analysis.

Replace the VID and PID with your USB network card ID, which you can check
using lsusb.

There is another point that we do not quite understand. We also triggered
this vulnerability on a Broadcom network card. However, the kernel message
indicated that the issue was due to the brcmfmac firmware. Using lsusb, we
discovered that this chip also uses the rt2x00 chipset. Could you please
clarify whether you can address this issue as well, or should we notify
Broadcom?
