Overview

CVE-2022-49954 is a medium-severity vulnerability. It was published on June 18, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

Input: iforce - wake up after clearing IFORCE_XMIT_RUNNING flag

syzbot is reporting hung task at __input_unregister_device() [1], for

iforce_close() waiting at wait_event_interruptible() with dev->mutex held

is blocking input_disconnect_device() from __input_unregister_device().

It seems that the cause is simply that commit c2b27ef672992a20 ("Input:

iforce - wait for command completion when closing the device") forgot to

call wake_up() after clear_bit().

Fix this problem by introducing a helper that calls clear_bit() followed

by wake_up_all().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
