CVE-2022-50733

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: idmouse: fix an uninit-value in idmouse_open<br /> <br /> In idmouse_create_image, if any ftip_command fails, it will<br /> go to the reset label. However, this leads to the data in<br /> bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check<br /> for valid image incurs an uninitialized dereference.<br /> <br /> Fix this by moving the check before reset label since this<br /> check only be valid if the data after bulk_in_buffer[HEADER]<br /> has concrete data.<br /> <br /> Note that this is found by KMSAN, so only kernel compilation<br /> is tested.
