CVE-2022-42326

Xenstore: Guests can create arbitrary number of nodes via transactions
T[his CNA information record relates to multiple CVEs; the text explains
which aspects/vulnerabilities correspond to which CVE.] In case a node has
been created in a transaction and it is later deleted in the same
transaction, the transaction will be terminated with an error. As this
error is encountered only when handling the deleted node at transaction
finalization, the transaction will have been performed partially and
without updating the accounting information. This will enable a malicious
guest to create arbitrary number of nodes.
