**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to the s390/cio component of the Linux kernel and involves incorrect control of resource identifiers. This can lead to a denial of service when an FCES path-event occurs on a device without an attached driver or if the driver does not provide the `path event` function. The problem arises because the kernel does not verify the driver availability before calling the `path event` function, potentially resulting in a kernel panic. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
