| 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-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-2017-5579 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 6.5 Medium |
| Memory leak in the serial_exit_core function in hw/char/serial.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-2017-14167 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 8.8 High |
| Integer overflow in the load_multiboot function in hw/i386/multiboot.c in QEMU (aka Quick Emulator) allows local guest OS users to execute arbitrary code on the host via crafted multiboot header address values, which trigger an out-of-bounds write. | ||||
| CVE-2017-15268 | 2 Qemu, Redhat | 3 Qemu, Enterprise Linux, Openstack | 2025-04-20 | N/A |
| Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c. | ||||
| CVE-2017-15038 | 1 Qemu | 1 Qemu | 2025-04-20 | N/A |
| Race condition in the v9fs_xattrwalk function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS users to obtain sensitive information from host heap memory via vectors related to reading extended attributes. | ||||
| CVE-2017-16845 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2025-04-20 | 10.0 Critical |
| hw/input/ps2.c in Qemu does not validate 'rptr' and 'count' values during guest migration, leading to out-of-bounds access. | ||||
| CVE-2017-5552 | 1 Qemu | 1 Qemu | 2025-04-20 | 6.5 Medium |
| Memory leak in the virgl_resource_attach_backing function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING commands. | ||||
| CVE-2017-5667 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 6.5 Medium |
| The sdhci_sdma_transfer_multi_blocks function in hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds heap access and crash) or execute arbitrary code on the QEMU host via vectors involving the data transfer length. | ||||
| CVE-2017-11434 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-20 | 5.5 Medium |
| The dhcp_decode function in slirp/bootp.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) via a crafted DHCP options string. | ||||
| 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. | ||||

| The vga display update in mis-calculated the region for the dirty bitmap snapshot in case split screen mode is used causing a denial of service (assertion failure) in the cpu_physical_memory_snapshot_get_dirty function. | ||||
| 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. | ||||
