Doc Text:
A flaw was found in QEMU. The PCIE SR-IOV emulation within QEMU incorrectly handles write masks for the VF Enable bit. This vulnerability allows an attacker with adjacent network access to trigger unexpected behavior. Mishandling occurs due to a logic error in hw/pci/pcie_sriov.c. Exploitation involves crafting a malicious network packet that can result in a denial of service.
