Description Ganesh 2026-07-28 17:58:54 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Accessing the vNUMA configuration data of a guest is still possible when
domain destruction has already started.  The cleaning up of that
configuration information is not synchronized with its retrieval by a
device model controlling the guest.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
