CVE-2024-26328 | 1 Qemu | 1 Qemu | 2025-05-07 | 6 Medium |
An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c does not set NumVFs to PCI_SRIOV_TOTAL_VF, and thus interaction with hw/nvme/ctrl.c is mishandled. | ||||
CVE-2024-26327 | 2 Qemu, Redhat | 2 Qemu, Enterprise Linux | 2025-05-07 | 5.3 Medium |
An issue was discovered in QEMU 7.1.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c mishandles the situation where a guest writes NumVFs greater than TotalVFs, leading to a buffer overflow in VF implementations. | ||||
CVE-2024-3567 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-06 | 5.5 Medium |
A flaw was found in QEMU. An assertion failure was present in the update_sctp_checksum() function in hw/net/net_tx_pkt.c when trying to calculate the checksum of a short-sized fragmented packet. This flaw allows a malicious guest to crash QEMU and cause a denial of service condition. | ||||
CVE-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2025-05-06 | 4.9 Medium |
A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak. | ||||
CVE-2022-3872 | 1 Qemu | 1 Qemu | 2025-05-05 | 8.6 High |
An off-by-one read/write issue was found in the SDHCI device of QEMU. It occurs when reading/writing the Buffer Data Port Register in sdhci_read_dataport and sdhci_write_dataport, respectively, if data_count == block_size. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | ||||
CVE-2023-6683 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-02 | 6.5 Medium |
A flaw was found in the QEMU built-in VNC server while processing ClientCutText messages. The qemu_clipboard_request() function can be reached before vnc_server_cut_text_caps() was called and had the chance to initialize the clipboard peer, leading to a NULL pointer dereference. This could allow a malicious authenticated VNC client to crash QEMU and trigger a denial of service. | ||||
CVE-2022-2962 | 1 Qemu | 1 Qemu | 2025-04-23 | 7.8 High |
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possibly leading to a stack or heap overflow. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service condition. | ||||
CVE-2016-9381 | 2 Citrix, Qemu | 2 Xenserver, Qemu | 2025-04-20 | 7.5 High |
Race condition in QEMU in Xen allows local x86 HVM guest OS administrators to gain privileges by changing certain data on shared rings, aka a "double fetch" vulnerability. | ||||
CVE-2016-10028 | 1 Qemu | 1 Qemu | 2025-04-20 | 5.5 Medium |
The virgl_cmd_get_capset function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) built with Virtio GPU Device emulator support allows local guest OS users to cause a denial of service (out-of-bounds read and process crash) via a VIRTIO_GPU_CMD_GET_CAPSET command with a maximum capabilities size with a value of 0. | ||||
CVE-2016-9922 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Openstack | 2025-04-20 | 5.5 Medium |
The cirrus_do_copy function in hw/display/cirrus_vga.c in QEMU (aka Quick Emulator), when cirrus graphics mode is VGA, allows local guest OS privileged users to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving blit pitch values. | ||||
CVE-2015-8619 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 7.5 High |
The Human Monitor Interface support in QEMU allows remote attackers to cause a denial of service (out-of-bounds write and application crash). | ||||
CVE-2015-8666 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 7.9 High |
Heap-based buffer overflow in QEMU, when built with the Q35-chipset-based PC system emulator. | ||||
CVE-2016-10029 | 1 Qemu | 1 Qemu | 2025-04-20 | 5.5 Medium |
The virtio_gpu_set_scanout function in QEMU (aka Quick Emulator) built with Virtio GPU Device emulator support allows local guest OS users to cause a denial of service (out-of-bounds read and process crash) via a scanout id in a VIRTIO_GPU_CMD_SET_SCANOUT command larger than num_scanouts. | ||||
CVE-2016-10155 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 6.0 Medium |
Memory leak in hw/watchdog/wdt_i6300esb.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations. | ||||
CVE-2015-8567 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2025-04-20 | 7.7 High |
Memory leak in net/vmxnet3.c in QEMU allows remote attackers to cause a denial of service (memory consumption). | ||||

Local privilege escalation vulnerability in the Gentoo QEMU package before 2.5.0-r1. | ||||
CVE-2015-8568 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 6.5 Medium |
Memory leak in QEMU, when built with a VMWARE VMXNET3 paravirtual NIC emulator support, allows local guest users to cause a denial of service (host memory consumption) by trying to activate the vmxnet3 device repeatedly. | ||||
CVE-2015-7504 | 4 Debian, Qemu, Redhat and 1 more | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-20 | 8.8 High |
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode. | ||||
CVE-2015-8504 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 6.5 Medium |
Qemu, when built with VNC display driver support, allows remote attackers to cause a denial of service (arithmetic exception and application crash) via crafted SetPixelFormat messages from a client. | ||||
