What to do
AI-suggested
A fix has been implemented in the Linux kernel to verify the presence of the USB device serial string before accessing it in the cp2615 driver. Users should update to the fixed kernel version once available. No other mitigation steps are indicated.
Description
A vulnerability in the Linux kernel cp2615 driver could cause a NULL-pointer dereference during device probe if the USB device serial string is missing. This occurs because the driver uses the serial string as the i2c adapter name without verifying its existence. The issue has been fixed by adding a check to ensure the serial number exists before accessing it.
