 domctl lock open to abuse

-----BEGIN PGP SIGNED MESSAGE-----

     Xen Security Advisory CVE-2026-42489,CVE-2026-42490 / XSA-492
                               version 3

                       domctl lock open to abuse

UPDATES IN VERSION 3
====================

Public release.

ISSUE DESCRIPTION
=================

To create and manage guests, domctl operations are used by the control
domain, a possible Xenstore domain, or by a domain controlling a
particular guest.  Some of these operations may not be executed in
parallel, so a system-wide lock is used.  The way that lock is acquired
is, however, not providing any fairness.  This is CVE-2026-42489.

Furthermore, with XSM/Flask in use, the lock acquire will, for some
operations, occur ahead of any permission checking.  This is
CVE-2026-42490.

IMPACT
======

A less privileged entity may stall an equally or more privileged entity,
potentially leading to a Denial od Service (DoS) of up to the entire
host.

VULNERABLE SYSTEMS
==================

All Xen versions from 3.3 onwards are vulnerable.  Earlier versions use
a different locking operation, but may also be vulnerable.

MITIGATION
==========

There is no known mitigation.

CREDITS
=======

This issue was discovered by Andrew Cooper of Citrix.

RESOLUTION
==========

Applying the appropriate set of attached patches resolves this issue.

NOTE: The staging and 4.21 patches include an adjustment to the default
Flask policy.  When custom policies are in use, a respective change
will need making there.

Note that patches for released versions are generally prepared to
apply to the stable branches, and may not apply cleanly to the most
recent release tarball.  Downstreams are encouraged to update to the
tip of the stable branch before applying these patches.

DEPLOYMENT DURING EMBARGO
=========================

Deployment of the patches and/or mitigations described above (or
others which are substantially similar) is permitted during the
embargo, even on public-facing systems with untrusted guest users and
administrators.

But: Distribution of updated software is prohibited (except to other
members of the predisclosure list).

Predisclosure list members who wish to deploy significantly different
patches and/or mitigations, please contact the Xen Project Security
Team.

(Note: this during-embargo deployment notice is retained in
post-embargo publicly released Xen Project advisories, even though it
is then no longer applicable.  This is to enable the community to have
oversight of the Xen Project Security Team's decisionmaking.)

For more information about permissible uses of embargoed information,
consult the Xen Project community's agreed Security Policy:
