hw/pci/pcie_sriov.c in QEMU through 10.0.3 mishandles the VF Enable bit write mask, a related issue to CVE-2024-26327.
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.
