CVE-2025-54567 [MEDIUM] CWE-684 qemu-kvm: QEMU SR-IOV Enable Mask Vulnerability
qemu-kvm: QEMU SR-IOV Enable Mask Vulnerability
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.
Mitigation: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
