Description OSIDB Bzimport 2026-03-25 11:05:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: usb: kaweth: validate USB endpoints

The kaweth driver should validate that the device it is probing has the
proper number and types of USB endpoints it is expecting before it binds
to it.  If a malicious device were to not have the same urbs the driver
will crash later on when it blindly accesses these endpoints.
