**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a race condition in the Linux kernel, specifically in the `register winch irq()` function. This function is part of the User-Mode Linux (UML) subsystem. The race condition occurs when an interrupt may happen before the winch is added to the `winch handlers` list, leading to a situation where a winch that is scheduled to be freed or has already been freed is added to the list, causing a panic later in `winch cleanup()`. The estimated number of potentially affected devices worldwide is not provided. There is no information about real-world incidents where this issue was exploited. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
