How to fix?

Upgrade SLES:15.5 kernel-devel to version 5.14.21-150500.55.113.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

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().
