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.
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-2017-13673 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-20 N/A
