+description = """The Use-After-Free bug mentioned by #2440 **has not been solved**, but the same crash is not reproducable in the later versions. After reviewing the code, I found an initiailized address space `proxy->modern_cfg_mem_as` introduced by  [`55fa4be`](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-sandbox/workbench/workbench.html "Inspect Commit Details") in `virtio_pci@hw/virtio/virtio-pci.c` will not be destroyed if the later realization is failed. 
+This will cause memory leak of the device object, which has unused reference and will not be destroyed.
+
+Relative Code in `virtio_pci_realize@virtio-pci.c`:
+
+```c
+/* subclasses can enforce modern, so do this unconditionally */
+memory_region_init(&proxy->modern_bar, OBJECT(proxy), "virtio-pci",
+                    /* PCI BAR regions must be powers of 2 */
+                    pow2ceil(proxy->notify.offset + proxy->notify.size));
+
+address_space_init(&proxy->modern_cfg_mem_as, &proxy->modern_bar,
+                    "virtio-pci-cfg-mem-as");
+
+if (proxy->disable_legacy == ON_OFF_AUTO_AUTO) {
+    proxy->disable_legacy = pcie_port ? ON_OFF_AUTO_ON : ON_OFF_AUTO_OFF;
+}
+```"""
+reproduce = """```bash
+cat <<EOF | qemu-system-i386 -M q35 -nodefaults -chardev stdio,id=char0 -mon char0 -device pcie-pci-bridge,id=br1,bus=pcie.0

+**This will cause UAF report in version `9.0.2`, but will not in `9.2.0`,** despite the bug still existing in code."""
