Memory leak in hw/9pfs/9p.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 FileOperations.
CVE-2016-9913 1 Qemu 1 Qemu 2026-06-17 4.9 MEDIUM 6.5 MEDIUM
Memory leak in the v9fs_device_unrealize_common function in hw/9pfs/9p.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) via vectors involving the order of resource cleanup.
CVE-2016-9912 1 Qemu 1 Qemu 2026-06-17 4.9 MEDIUM 6.5 MEDIUM
Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while destroying gpu resource object in 'virtio_gpu_resource_destroy'. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.
CVE-2016-9911 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2026-06-17 4.9 MEDIUM 6.5 MEDIUM
Quick Emulator (Qemu) built with the USB EHCI Emulation support is vulnerable to a memory leakage issue. It could occur while processing packet data in 'ehci_init_transfer'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host.
CVE-2016-9908 1 Qemu 1 Qemu 2026-06-17 2.1 LOW 3.3 LOW
Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to an information leakage issue. It could occur while processing 'VIRTIO_GPU_CMD_GET_CAPSET' command. A guest user/process could use this flaw to leak contents of the host memory bytes.
CVE-2016-9907 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2026-06-17 4.9 MEDIUM 6.5 MEDIUM
Quick Emulator (Qemu) built with the USB redirector usb-guest support is vulnerable to a memory leakage flaw. It could occur while destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host.
