This is the exact same bug as the following patches: 381583845d19 ("HID: cp2112: prevent a buffer overflow in cp2112_xfer()") 690b2549b195 ("i2c: ismt: prevent memory corruption in ismt_access()") The patch should fix the memory corruption but there may be other issues with this code. regards, dan carpenter
