Description Ganesh 2026-07-28 17:58:18 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.

A guest started with Populated on Demand enabled (PoD) can attempt to
reclaim pages which aren't regular guest RAM.  This can cause corruption
of memory management state in Xen.

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