      Problem description:

      • The virtio-win drivers have a critical bug which causes BSOD and Data Corruption. While RHEL has already shipped the fix in RHEL-145873, we need the container-native-virtualization/virtio-win-rhel9 images updated as well, as these are used by OpenShift Virtualization when customers are installing new VMs. Currently new VMs on OpenShift Virtualization are being installed with the old buggy driver - this causes BSOD and Data Corruption.

      Steps to reproduce:

      We need virtio-win-1.9.53-0.el9_6 or higher (released in RHBA-2026:2280). But all the recent container-native-virtualization/virtio-win-rhel9, even those released in the last few days are shipping with older drivers:

      Latest of 4.21, 4.20 and 4.18 as examples:
