CVE-2017-5526 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 6.5 Medium
Memory leak in hw/audio/es1370.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-2022-4172 3 Fedoraproject, Qemu, Redhat 3 Fedora, Qemu, Enterprise Linux 2025-04-14 6.5 Medium
An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.
CVE-2022-4144 3 Fedoraproject, Qemu, Redhat 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more 2025-04-14 6.5 Medium
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
CVE-2015-4037 1 Qemu 1 Qemu 2025-04-12 N/A
The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program.
CVE-2014-0182 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Heap-based buffer overflow in the virtio_load function in hw/virtio/virtio.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted config length in a savevm image.
CVE-2016-3712 6 Canonical, Citrix, Debian and 3 more 12 Ubuntu Linux, Xenserver, Debian Linux and 9 more 2025-04-12 5.5 Medium
Integer overflow in the VGA module in QEMU allows local guest OS users to cause a denial of service (out-of-bounds read and QEMU process crash) by editing VGA registers in VBE mode.
CVE-2014-5263 1 Qemu 1 Qemu 2025-04-12 N/A
vmstate_xhci_event in hw/usb/hcd-xhci.c in QEMU 1.6.0 does not terminate the list with the VMSTATE_END_OF_LIST macro, which allows attackers to cause a denial of service (out-of-bounds access, infinite loop, and memory corruption) and possibly gain privileges via unspecified vectors.
CVE-2013-4150 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
The virtio_net_load function in hw/net/virtio-net.c in QEMU 1.5.0 through 1.7.x before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors in which the value of curr_queues is greater than max_queues, which triggers an out-of-bounds write.
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.
CVE-2014-3615 5 Canonical, Debian, Opensuse and 2 more 13 Ubuntu Linux, Debian Linux, Opensuse and 10 more 2025-04-12 N/A
The VGA emulator in QEMU allows local guest users to read host memory by setting the display to a high resolution.
CVE-2014-0223 3 Qemu, Redhat, Suse 4 Qemu, Enterprise Linux, Openstack and 1 more 2025-04-12 N/A
Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a large image size, which triggers a buffer overflow or out-of-bounds read.
CVE-2014-0150 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Integer overflow in the virtio_net_handle_mac function in hw/net/virtio-net.c in QEMU 2.0 and earlier allows local guest users to execute arbitrary code via a MAC addresses table update request, which triggers a heap-based buffer overflow.
CVE-2014-9718 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 N/A
The (1) BMDMA and (2) AHCI HBA interfaces in the IDE functionality in QEMU 1.0 through 2.1.3 have multiple interpretations of a function's return value, which allows guest OS users to cause a host OS denial of service (memory consumption or infinite loop, and system crash) via a PRDT with zero complete sectors, related to the bmdma_prepare_buf and ahci_dma_prepare_buf functions.
CVE-2016-3710 7 Canonical, Citrix, Debian and 4 more 17 Ubuntu Linux, Xenserver, Debian Linux and 14 more 2025-04-12 8.8 High
