CVE-2015-5225 3 Fedoraproject, Qemu, Redhat 4 Fedora, Qemu, Enterprise Linux and 1 more 2025-04-12 N/A
Buffer overflow in the vnc_refresh_server_surface function in the VNC display driver in QEMU before 2.4.0.1 allows guest users to cause a denial of service (heap memory corruption and process crash) or possibly execute arbitrary code on the host via unspecified vectors, related to refreshing the server display surface.
CVE-2016-2198 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 5.5 Medium
QEMU (aka Quick Emulator) built with the USB EHCI emulation support is vulnerable to a null pointer dereference flaw. It could occur when an application attempts to write to EHCI capabilities registers. A privileged user inside quest could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2015-8743 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 7.1 High
QEMU (aka Quick Emulator) built with the NE2000 device emulation support is vulnerable to an OOB r/w access issue. It could occur while performing 'ioport' r/w operations. A privileged (CAP_SYS_RAWIO) user/process could use this flaw to leak or corrupt QEMU memory bytes.
CVE-2016-2841 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2025-04-12 N/A
The ne2000_receive function in the NE2000 NIC emulation support (hw/net/ne2000.c) in QEMU before 2.5.1 allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via crafted values for the PSTART and PSTOP registers, involving ring buffer control.
CVE-2016-7155 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 4.4 Medium
hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (out-of-bounds access or infinite loop, and QEMU process crash) via a crafted page count for descriptor rings.
CVE-2015-6855 6 Arista, Canonical, Debian and 3 more 7 Eos, Ubuntu Linux, Debian Linux and 4 more 2025-04-12 7.5 High
hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.
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-2013-4534 1 Qemu 1 Qemu 2025-04-12 N/A
Buffer overflow in hw/intc/openpic.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via vectors related to IRQDest elements.
