| hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap interface. | ||||
| CVE-2015-7512 | 4 Debian, Oracle, Qemu and 1 more | 10 Debian Linux, Linux, Qemu and 7 more | 2025-04-12 | 9.0 Critical |
| Buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU, when a guest NIC has a larger MTU, allows remote attackers to cause a denial of service (guest OS crash) or execute arbitrary code via a large packet. | ||||
| CVE-2015-8701 | 1 Qemu | 1 Qemu | 2025-04-12 | 6.5 Medium |
| QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. 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. | ||||
| CVE-2015-8743 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 7.1 High |
| QEMU (aka Quick Emulator) built with the NE2000 device emulation support is vulnerable to an OOB r/w access issue. It could occur while performing 'ioport' r/w operations. A privileged (CAP_SYS_RAWIO) user/process could use this flaw to leak or corrupt QEMU memory bytes. | ||||
| CVE-2016-1981 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS. | ||||
| CVE-2016-2538 | 1 Qemu | 1 Qemu | 2025-04-12 | N/A |
| Multiple integer overflows in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 allow local guest OS administrators to cause a denial of service (QEMU process crash) or obtain sensitive host memory information via a remote NDIS control message packet that is mishandled in the (1) rndis_query_response, (2) rndis_set_response, or (3) usb_net_handle_dataout function. | ||||
| CVE-2015-8558 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |

| CVE-2016-1922 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 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. | ||||
| CVE-2016-2198 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with the USB EHCI emulation support is vulnerable to a null pointer dereference flaw. It could occur when an application attempts to write to EHCI capabilities registers. A privileged user inside quest could use this flaw to crash the QEMU process instance resulting in DoS. | ||||
| CVE-2016-2392 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2025-04-12 | N/A |
| The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 does not properly validate USB configuration descriptor objects, which allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet. | ||||
| CVE-2016-2858 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2025-04-12 | 6.5 Medium |
| QEMU, when built with the Pseudo Random Number Generator (PRNG) back-end support, allows local guest OS users to cause a denial of service (process crash) via an entropy request, which triggers arbitrary stack based allocation and memory corruption. | ||||
| CVE-2016-6888 | 3 Debian, Qemu, Redhat | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-12 | 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-2016-7423 | 1 Qemu | 1 Qemu | 2025-04-12 | 4.4 Medium |
| The mptsas_process_scsi_io_request function in QEMU (aka Quick Emulator), when built with LSI SAS1068 Host Bus emulation support, allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors involving MPTSASRequest objects. | ||||
