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

Description The issue is related to the creation of orphaned Xenstore nodes by guests. This occurs when a malicious guest creates multiple nodes inside a transaction, resulting in an error. The cleanup after the error does not remove all nodes already created, allowing nodes without a valid parent to be made permanent in the database when the transaction is committed. This can lead to a denial of service.

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