There is no fixed version for Centos:9 kernel-debug-uki-virt.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-uki-virt package and not the kernel-debug-uki-virt 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:

Input: uinput - zero-initialize uinput_ff_upload_compat to avoid info leak

Struct ff_effect_compat is embedded twice inside uinput_ff_upload_compat, contains internal padding. In particular, there is a hole after struct ff_replay to satisfy alignment requirements for the following union member. Without clearing the structure, copy_to_user() may leak stack data to userspace.

Initialize ff_up_compat to zero before filling valid fields.
