CVSS: 6.0EPSS: 0%CPEs: 10EXPL: 0CVE-2016-7466 – Qemu: usb: xhci memory leakage during device unplug
https://notcve.org/view.php?id=CVE-2016-7466
Memory leak in the usb_xhci_exit function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator), when the xhci uses msix, allows local guest OS administrators to cause a denial of service (memory consumption and possibly QEMU process crash) by repeatedly unplugging a USB device. Fuga de memoria en la función usb_xhci_exit en hw/usb/hcd-xhci.c en QEMU (también conocido como Quick Emulator), cuando el xhci utiliza msix, permite a administradores locales del SO invitado provocar una denegación de servicio (consumo de memoria y posible caída del proceso QEMU) desconectando repetidamente un dispositivo USB. A memory-leak flaw was found in the Quick Emulator(QEMU) built with USB xHCI controller emulation support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly resulted in leaking host memory, which affected other services on the host. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=b53dd4495ced2432a0b652ea895e651d07336f7e http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/09/19/8 http://www.openwall.com/lists/oss-security/2016/09/20/3 http://www.securityfocus.com/bid/93029 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg02773.html https:&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-772: Missing Release of Resource after Effective Lifetime •
