Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability has been resolved in the Linux kernel related to the ksmbd module. The issue arises when the
wait event timeout() function sets the state of the current task to TASK UNINTERRUPTIBLE before performing a condition check. As a result, ksmbd durable scavenger alive() attempts to acquire a mutex while the task is already in a sleeping state, triggering a warning from the scheduler. The warning indicates that blocking operations should not be called when the task is not in the TASK RUNNING state. The mutex lock is unnecessary in ksmbd durable scavenger alive().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
