|---|---|---|---|---|
| CVE-2016-2197 | 1 Qemu | 1 Qemu | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure (FIS) and Command List Block (CLB) entries. A privileged user inside guest could use this flaw to crash the QEMU process instance resulting in DoS. | ||||
| CVE-2015-3456 | 3 Qemu, Redhat, Xen | 7 Qemu, Enterprise Linux, Enterprise Virtualization and 4 more | 2025-04-12 | N/A |
| The Floppy Disk Controller (FDC) in QEMU, as used in Xen 4.5.x and earlier and KVM, allows local guest users to cause a denial of service (out-of-bounds write and guest crash) or possibly execute arbitrary code via the (1) FD_CMD_READ_ID, (2) FD_CMD_DRIVE_SPECIFICATION_COMMAND, or other unspecified commands, aka VENOM. | ||||
| CVE-2016-1981 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with the e1000 NIC emulation support is vulnerable to an infinite loop issue. It could occur while processing data via transmit or receive descriptors, provided the initial receive/transmit descriptor head (TDH/RDH) is set outside the allocated descriptor buffer. A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS. | ||||
| 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-2016-7116 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 6.0 Medium |
| Directory traversal vulnerability in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allows local guest OS administrators to access host files outside the export path via a .. (dot dot) in an unspecified string. | ||||
| CVE-2016-7995 | 2 Opensuse, Qemu | 2 Leap, Qemu | 2025-04-12 | 6.0 Medium |
| Memory leak in the ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) via a large number of crafted buffer page select (PG) indexes. | ||||
| CVE-2016-1568 | 3 Debian, Qemu, Redhat | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-12 | 8.8 High |
| Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command. | ||||
| 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-2016-9106 | 3 Debian, Opensuse, Qemu | 3 Debian Linux, Leap, Qemu | 2025-04-12 | 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. | ||||
| 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-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-2015-8744 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It occurs when a guest sends a Layer-2 packet smaller than 22 bytes. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS. | ||||
| CVE-2016-7156 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 4.4 Medium |
| The pvscsi_convert_sglist function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging an incorrect cast. | ||||
