In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: verify the expected usb_endpoints are present
The bug arises when a USB device claims to be an ATH9K but doesn't
have the expected endpoints. (In this case there was an interrupt
endpoint where the driver expected a bulk endpoint.) The kernel
needs to be able to handle such devices without getting an internal error.
