LIN1019-11099 : Security Advisory - linux - CVE-2021-46932

Created: Feb 27, 2024 Updated: Mar 19, 2024

Resolved Date: Mar 19, 2024

Found In Version: 10.19.45.1

Severity: Standard

Applicable for: Wind River Linux LTS 19

Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:

Input: appletouch - initialize work before device registration

Syzbot has reported warning in __flush_work(). This warning is caused by
work->func == NULL, which means missing work initialization.

This may happen, since input_dev->close() calls
cancel_work_sync(&dev->work), but dev->work initalization happens _after_
input_register_device() call.

So this patch moves dev->work initialization before registering input
device
