| CVE-2015-8558 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 5.5 Medium |
| The ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via a circular isochronous transfer descriptor (iTD) list. | ||||
| 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. | ||||

| 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-2016-7907 | 1 Qemu | 1 Qemu | 2025-04-12 | 4.4 Medium |
| The imx_fec_do_tx function in hw/net/imx_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags. | ||||
| CVE-2016-7909 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 4.4 Medium |
| The pcnet_rdra_addr function in hw/net/pcnet.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by setting the (1) receive or (2) transmit descriptor ring length to 0. | ||||
| CVE-2016-9907 | 3 Debian, Qemu, Redhat | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-12 | 6.5 Medium |
| Quick Emulator (Qemu) built with the USB redirector usb-guest support is vulnerable to a memory leakage flaw. It could occur while destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host. | ||||
| CVE-2016-2841 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2025-04-12 | N/A |
| 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-2016-9923 | 1 Qemu | 1 Qemu | 2025-04-12 | 5.5 Medium |
| Quick Emulator (Qemu) built with the 'chardev' backend support is vulnerable to a use after free issue. It could occur while hotplug and unplugging the device in the guest. A guest user/process could use this flaw to crash a Qemu process on the host resulting in DoS. | ||||
