Subject: Reply: A null-ptr crash in linux-6.4 usb driver
Date: Wed, 8 Nov 2023 07:40:08 +0000 [thread overview]
Message-ID: <043105feee62401f833a06ea480a3b1b@qianxin.com> (raw)
I have made a patch that simply checks for null pointer, but I am not sure if this will affect certain functions or logic. I hope you can check it carefully.
