Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a large image size, which triggers a buffer overflow or out-of-bounds read.
CVE-2014-2894 1 Qemu 1 Qemu 2025-04-12 7.2 HIGH N/A
Off-by-one error in the cmd_smart function in the smart self test in hw/ide/core.c in QEMU before 2.0 allows local users to have unspecified impact via a SMART EXECUTE OFFLINE command that triggers a buffer underflow and memory corruption.

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-2016-6888 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 2.1 LOW 4.4 MEDIUM
Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference.
CVE-2016-9845 1 Qemu 1 Qemu 2025-04-12 2.1 LOW 6.5 MEDIUM
QEMU (aka Quick Emulator) 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_INFO' 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 2025-04-12 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.
CVE-2013-4540 2 Opensuse, Qemu 2 Opensuse, Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in scoop_gpio_handler_update in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a large (1) prev_level, (2) gpio_level, or (3) gpio_dir value in a savevm image.
CVE-2016-1568 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 6.9 MEDIUM 8.8 HIGH
Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.
CVE-2013-6399 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Array index error in the virtio_load function in hw/virtio/virtio.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image.
CVE-2013-4150 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
The virtio_net_load function in hw/net/virtio-net.c in QEMU 1.5.0 through 1.7.x before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors in which the value of curr_queues is greater than max_queues, which triggers an out-of-bounds write.
CVE-2016-2197 1 Qemu 1 Qemu 2025-04-12 2.1 LOW 5.5 MEDIUM
QEMU (aka Quick Emulator) built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure (FIS) and Command List Block (CLB) entries.
