**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the rtmutex in the Linux kernel, where the `rt mutex handle deadlock()` function is called with `rt mutex::wait lock` held. In the deadlock case, it emits a warning and goes into an endless scheduling loop with the lock held, triggering the 'scheduling in atomic' warning. The fix involves unlocking `rt mutex::wait lock` in the dead lock case before issuing the warning and dropping into the schedule loop. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
