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-2016-1922 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 5.5 Medium
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue.
CVE-2016-9907 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 6.5 Medium
Quick Emulator (Qemu) built with the USB redirector usb-guest support is vulnerable to a memory leakage flaw. It could occur while destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host.
CVE-2014-3640 4 Canonical, Debian, Qemu and 1 more 8 Ubuntu Linux, Debian Linux, Qemu and 5 more 2025-04-12 N/A
The sosendto function in slirp/udp.c in QEMU before 2.1.2 allows local users to cause a denial of service (NULL pointer dereference) by sending a udp packet with a value of 0 in the source port and address, which triggers access of an uninitialized socket.
CVE-2014-2894 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Off-by-one error in the cmd_smart function in the smart self test in hw/ide/core.c in QEMU before 2.0 allows local users to have unspecified impact via a SMART EXECUTE OFFLINE command that triggers a buffer underflow and memory corruption.
CVE-2013-4149 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Buffer overflow in virtio_net_load function in net/virtio-net.c in QEMU 1.3.0 through 1.7.x before 1.7.2 might allow remote attackers to execute arbitrary code via a large MAC table.
CVE-2016-9106 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2025-04-12 6.0 Medium
Memory leak in the v9fs_write function in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) by leveraging failure to free an IO vector.
CVE-2016-1568 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 8.8 High
Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.
CVE-2013-4148 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Integer signedness error in the virtio_net_load function in hw/net/virtio-net.c in QEMU 1.x before 1.7.2 allows remote attackers to execute arbitrary code via a crafted savevm image, which triggers a buffer overflow.
CVE-2013-4539 1 Qemu 1 Qemu 2025-04-12 N/A
Multiple buffer overflows in the tsc210x_load function in hw/input/tsc210x.c in QEMU before 1.7.2 might allow remote attackers to execute arbitrary code via a crafted (1) precision, (2) nextprecision, (3) function, or (4) nextfunction value in a savevm image.
CVE-2015-3456 3 Qemu, Redhat, Xen 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more 2025-04-12 N/A
The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM.
CVE-2014-5388 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2025-04-12 N/A
Off-by-one error in the pci_read function in the ACPI PCI hotplug interface (hw/acpi/pcihp.c) in QEMU allows local guest users to obtain sensitive information and have other unspecified impact related to a crafted PCI device that triggers memory corruption.
CVE-2015-8701 1 Qemu 1 Qemu 2025-04-12 6.5 Medium
QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue.
CVE-2011-3346 3 Qemu, Redhat, Xen 3 Qemu, Enterprise Linux, Xen 2025-04-12 N/A
Buffer overflow in hw/scsi-disk.c in the SCSI subsystem in QEMU before 0.15.2, as used by Xen, might allow local guest users with permission to access the CD-ROM to cause a denial of service (guest crash) via a crafted SAI READ CAPACITY SCSI command. NOTE: this is only a vulnerability when root has manually modified certain permissions or ACLs.
