Description
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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability exists in the Linux kernel's kaweth USB driver. The driver fails to properly validate that a USB device it is probing has the correct number and types of USB endpoints before binding to it.

If a malicious USB device does not have the expected USB Request Blocks (URBs) or endpoints, the driver may later crash when it tries to access these endpoints blindly.


How can this vulnerability impact me? :

This vulnerability can cause the Linux kernel to crash when the kaweth driver interacts with a malicious USB device that does not have the expected endpoints.

Such crashes can lead to denial of service (DoS) conditions, potentially disrupting system availability.
