CVE-2026-62437

When guests are terminated, various pieces of cleanup need carrying out.<br /> The cleaning up of PCI devices which were assigned to guests, and the<br /> associated removal of tracking structures for IRQs used by the devices<br /> occurs relatively early in the process. Unfortunately after that point<br /> the guest about to be terminated could cause its device model (DM) to<br /> re-establish such tracking structures, by having it bind one or more IRQs<br /> anew. While some of those tracking structures would still be cleaned up<br /> later on, at least one would not be.
