CVE-2025-54566 | 1 Qemu | 1 Qemu | 2025-07-25 | 4.2 Medium |
hw/pci/pcie_sriov.c in QEMU through 10.0.3 has a migration state inconsistency, a related issue to CVE-2024-26327. | ||||
CVE-2025-54567 | 1 Qemu | 1 Qemu | 2025-07-25 | 4.2 Medium |
hw/pci/pcie_sriov.c in QEMU through 10.0.3 mishandles the VF Enable bit write mask, a related issue to CVE-2024-26327. | ||||
CVE-2024-24474 | 1 Qemu | 1 Qemu | 2025-06-25 | 8.8 High |
QEMU before 8.2.0 has an integer underflow, and resultant buffer overflow, via a TI command when an expected non-DMA transfer length is less than the length of the available FIFO data. This occurs in esp_do_nodma in hw/scsi/esp.c because of an underflow of async_len. | ||||
CVE-2023-5088 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-06-12 | 6.4 Medium |
A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead (potentially overwriting the VM's boot code). This could be used, for example, by L2 guests with a virtual disk (vdiskL2) stored on a virtual disk of an L1 (vdiskL1) hypervisor to read and/or write data to LBA 0 of vdiskL1, potentially gaining control of L1 at its next reboot. | ||||
CVE-2023-6693 | 3 Fedoraproject, Qemu, Redhat | 4 Fedora, Qemu, Advanced Virtualization and 1 more | 2025-05-21 | 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-2024-8354 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-21 | 5.5 Medium |
A flaw was found in QEMU. An assertion failure was present in the usb_ep_get() function in hw/net/core.c when trying to get the USB endpoint from a USB device. This flaw may allow a malicious unprivileged guest user to crash the QEMU process on the host and cause a denial of service condition. | ||||
CVE-2024-6505 | 2 Qemu, Redhat | 3 Qemu, Advanced Virtualization, Enterprise Linux | 2025-05-21 | 6.8 Medium |
A flaw was found in the virtio-net device in QEMU. When enabling the RSS feature on the virtio-net network card, the indirections_table data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host. | ||||
CVE-2022-3165 | 3 Fedoraproject, Qemu, Redhat | 3 Fedora, Qemu, Enterprise Linux | 2025-05-14 | 6.5 Medium |
An integer underflow issue was found in the QEMU VNC server while processing ClientCutText messages in the extended format. A malicious client could use this flaw to make QEMU unresponsive by sending a specially crafted payload message, resulting in a denial of service. | ||||
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-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-2017-10664 | 3 Debian, Qemu, Redhat | 11 Debian Linux, Qemu, Enterprise Linux and 8 more | 2025-04-20 | 7.5 High |
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. | ||||
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-2017-10806 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 5.5 Medium |
Stack-based buffer overflow in hw/usb/redirect.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (QEMU process crash) via vectors related to logging debug messages. | ||||
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-2014-0143 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Openstack | 2025-04-20 | N/A |
Multiple integer overflows in the block drivers in QEMU, possibly before 2.0.0, allow local users to cause a denial of service (crash) via a crafted catalog size in (1) the parallels_open function in block/parallels.c or (2) bochs_open function in bochs.c, a large L1 table in the (3) qcow2_snapshot_load_tmp in qcow2-snapshot.c or (4) qcow2_grow_l1_table function in qcow2-cluster.c, (5) a large request in the bdrv_check_byte_request function in block.c and other block drivers, (6) crafted cluster indexes in the get_refcount function in qcow2-refcount.c, or (7) a large number of blocks in the cloop_open function in cloop.c, which trigger buffer overflows, memory corruption, large memory allocations and out-of-bounds read and writes. | ||||
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. |
