CVE-2023-53548
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
net: usbnet: Fix WARNING in usbnet_start_xmit/usb_submit_urb
The syzbot fuzzer identified a problem in the usbnet driver:
This bug is caused by the fact that usbnet trusts the bulk endpoint addresses its probe routine receives in the driver_info structure, and it does not check to see that these endpoints actually exist and have the expected type and directions.
The fix is simply to add such a check.
