CVE-2022-50733:
Linux Kernel vulnerability analysis and mitigation
In the Linux kernel, the following vulnerability has been resolved:
usb: idmouse: fix an uninit-value in idmouse_open
In idmouse_create_image, if any ftip_command fails, it will go to the reset label. However, this leads to the data in bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this check only be valid if the data after bulk_in_buffer[HEADER] has concrete data.
Note that this is found by KMSAN, so only kernel compilation is tested.
