| 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-2015-5279 | 2 Qemu, Redhat | 4 Qemu, Enterprise Linux, Openstack and 1 more | 2025-04-12 | N/A |
| Heap-based buffer overflow in the ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via vectors related to receiving packets. | ||||
| CVE-2016-2391 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2025-04-12 | 5.0 Medium |
| The ohci_bus_start function in the USB OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors related to multiple eof_timers. | ||||
| CVE-2015-5158 | 1 Qemu | 1 Qemu | 2025-04-12 | 5.5 Medium |
| Stack-based buffer overflow in hw/scsi/scsi-bus.c in QEMU, when built with SCSI-device emulation support, allows guest OS users with CAP_SYS_RAWIO permissions to cause a denial of service (instance crash) via an invalid opcode in a SCSI command descriptor block. | ||||
| 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.
