Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A potential crash issue in the Linux kernel has been resolved. The vmbus driver, which can be built as a module, relies on the panic notifier infrastructure to perform certain operations when a panic event is detected. However, the panic notifier registration was done unconditionally in the module initialization routine, while the unregistering procedure was conditionally guarded and only executed if a specific capability was set. This issue has been fixed by unconditionally unregistering the panic notifier in the module's exit routine.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
