A flaw was found in the SR/IOV emulation support of QEMU. The register_vfs() function in hw/pci/pcie_sriov.c mishandled the situation where a guest writes NumVFs greater than TotalVFs, leading to a buffer overflow in VF (Virtual Function) implementations. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition.
