| Heap-based buffer overflow in the IDE subsystem in QEMU, as used in Xen 4.5.x and earlier, when the container has a CDROM drive enabled, allows local guest users to execute arbitrary code on the host via unspecified ATAPI commands. | ||||
| CVE-2015-6855 | 6 Arista, Canonical, Debian and 3 more | 7 Eos, Ubuntu Linux, Debian Linux and 4 more | 2025-04-12 | 7.5 High |
| hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash. | ||||
| CVE-2016-9846 | 1 Qemu | 1 Qemu | 2025-04-12 | 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. | ||||
| CVE-2015-8744 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It occurs when a guest sends a Layer-2 packet smaller than 22 bytes. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS. | ||||
| CVE-2015-8818 | 2 Qemu, Redhat | 2 Qemu, Openstack | 2025-04-12 | 5.5 Medium |
| The cpu_physical_memory_write_rom_internal function in exec.c in QEMU (aka Quick Emulator) does not properly skip MMIO regions, which allows local privileged guest users to cause a denial of service (guest crash) via unspecified vectors. | ||||
| CVE-2016-9776 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with the ColdFire Fast Ethernet Controller emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could use this issue to crash the QEMU process on the host leading to DoS. | ||||
| CVE-2016-7421 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 4.4 Medium |
| The pvscsi_ring_pop_req_descr function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit process IO loop to the ring size. | ||||
| CVE-2016-7170 | 3 Debian, Opensuse, Qemu | 3 Debian Linux, Leap, Qemu | 2025-04-12 | 4.4 Medium |

| CVE-2013-4544 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2025-04-12 | N/A |
| hw/net/vmxnet3.c in QEMU 2.0.0-rc0, 1.7.1, and earlier allows local guest users to cause a denial of service or possibly execute arbitrary code via vectors related to (1) RX or (2) TX queue numbers or (3) interrupt indices. NOTE: some of these details are obtained from third party information. | ||||
| CVE-2013-4541 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Openstack | 2025-04-12 | N/A |
| The usb_device_post_load function in hw/usb/bus.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted savevm image, related to a negative setup_len or setup_index value. | ||||
| CVE-2015-8701 | 1 Qemu | 1 Qemu | 2025-04-12 | 6.5 Medium |

It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue. | ||||
