CVE-2016-1922 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue.

Memory leak in hw/9pfs/9p-proxy.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in the proxy backend.
CVE-2016-9846 1 Qemu 1 Qemu 2025-04-12 4.9 MEDIUM 6.5 MEDIUM
QEMU (aka Quick Emulator) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while updating the cursor data in update_cursor_data_virgl. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.

The ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular isochronous transfer descriptor (iTD) list.
CVE-2016-8667 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2025-04-12 2.1 LOW 6.0 MEDIUM
