| An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition. | ||||
| CVE-2015-8818 | 2 Qemu, Redhat | 2 Qemu, Openstack | 2025-04-12 | 5.5 Medium |

| 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-2014-0222 | 3 Qemu, Redhat, Suse | 4 Qemu, Enterprise Linux, Openstack and 1 more | 2025-04-12 | N/A |
| Integer overflow in the qcow_open function in block/qcow.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service (crash) via a large L2 table in a QCOW version 1 image. | ||||
| CVE-2016-5106 | 3 Canonical, Debian, Qemu | 3 Ubuntu Linux, Debian Linux, Qemu | 2025-04-12 | 6.0 Medium |
| The megasas_dcmd_set_properties function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, allows local guest administrators to cause a denial of service (out-of-bounds write access) via vectors involving a MegaRAID Firmware Interface (MFI) command. | ||||
| 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. | ||||
