Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of QEMU installed on the remote Windows host is prior to 10.0.3 and therefore vulnerable to the following:

  - hw/pci/pcie_sriov.c in QEMU through 10.0.3 has a migration state inconsistency, a related issue to     CVE-2024-26327. (CVE-2025-54566)

  - 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. (CVE-2025-54567)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 12 / 13 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5983 advisory.

    Package        : qemu     CVE ID         : CVE-2025-54566 CVE-2025-54567

    This update removes the usage of the C (Credential) flag for the     binfmt_misc registration within the qemu-user package, as it allowed for     privilege escalation when running a suid/sgid binary under qemu-user.
    This means suid/sgid foreign-architecture binaries are not running with     elevated privileges under qemu-user anymore.  If you relied on this     behavior of qemu-user in the past (running suid/sgid foreign-arch     binaries), this will require changes to your deployment.

    In Bookworm the affected packages are qemu-user-static (and     qemu-user-binfmt) instead of qemu-user.

    Additionally, two security issues were fixed the in SR-IOV support     of QEMU system emulation.

    For the oldstable distribution (bookworm), these problems have been fixed     in version 1:7.2+dfsg-7+deb12u15.

    For the stable distribution (trixie), these problems have been fixed in     version 1:10.0.2+ds-2+deb13u1.

    We recommend that you upgrade your qemu packages.

    For the detailed security status of qemu please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/qemu
