CVE-2016-1922 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 2.1 LOW 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.

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.

The virtqueue_map_desc function in hw/virtio/virtio.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via a large I/O descriptor buffer length value.
CVE-2016-6835 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Enterprise Linux and 1 more 2025-04-12 2.1 LOW 6.0 MEDIUM
The vmxnet_tx_pkt_parse_headers function in hw/net/vmxnet_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (buffer over-read) by leveraging failure to check IP header length.
CVE-2013-4533 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in the pxa2xx_ssp_load function in hw/arm/pxa2xx.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via a crafted s->rx_level value in a savevm image.
CVE-2014-8106 1 Qemu 1 Qemu 2025-04-12 4.6 MEDIUM N/A
Heap-based buffer overflow in the Cirrus VGA emulator (hw/display/cirrus_vga.c) in QEMU before 2.2.0 allows local guest users to execute arbitrary code via vectors related to blit regions. NOTE: this vulnerability exists because an incomplete fix for CVE-2007-1320.
CVE-2016-9106 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2025-04-12 2.1 LOW 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.
