CVE-2022-42310 is fixed in xen on 1 platform, first by DEBIAN-CVE-2022-42310, released November 1, 2022. It is not reported as exploited. Patch Radar priority: Routine.
Xenstore: Guests can create orphaned Xenstore nodes By creating multiple nodes inside a transaction resulting in an error, a malicious guest can create orphaned nodes in the Xenstore data base, as the cleanup after the error will not remove all nodes already created. When the transaction is committed after this situation, nodes without a valid parent can be made permanent in the data base.
