How to fix?

There is no fixed version for Centos:9 rv.

NVD Description

Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

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.
