Overview
CVE-2022-50733 is a known-severity vulnerability. It was published on December 24, 2025.
Technical description
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.
