Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A issue in the Linux kernel has been identified where the
iforce close() function waits at wait event interruptible() with dev->mutex held, blocking input disconnect device() from input unregister device(). This is caused by a commit that forgot to call wake up() after clear bit(). The problem occurs when the IFORCE XMIT RUNNING flag is cleared.Recommendations
For the Linux kernel, introduce a helper that calls
clear bit() followed by wake up all() to fix the issue.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
