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.

The get_cmd function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check DMA length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command.
CVE-2013-4538 1 Qemu 1 Qemu 2025-04-12 N/A
Multiple buffer overflows in the ssd0323_load function in hw/display/ssd0323.c in QEMU before 1.7.2 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via crafted (1) cmd_len, (2) row, or (3) col values; (4) row_start and row_end values; or (5) col_star and col_end values in a savevm image.
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-2016-9104 3 Debian, Opensuse, Qemu 3 Debian Linux, Leap, Qemu 2025-04-12 4.4 Medium
Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.
CVE-2013-4529 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
Buffer overflow in hw/pci/pcie_aer.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large log_num value in a savevm image.
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-2015-4106 6 Canonical, Citrix, Debian and 3 more 8 Ubuntu Linux, Xenserver, Debian Linux and 5 more 2025-04-12 N/A
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
CVE-2016-2858 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 6.5 Medium
QEMU, when built with the Pseudo Random Number Generator (PRNG) back-end support, allows local guest OS users to cause a denial of service (process crash) via an entropy request, which triggers arbitrary stack based allocation and memory corruption.
CVE-2013-4530 1 Qemu 1 Qemu 2025-04-12 N/A
Buffer overflow in hw/ssi/pl022.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted tx_fifo_head and rx_fifo_head values in a savevm image.
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-2013-4527 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-12 N/A
