CVE-2016-8576 4 Debian, Opensuse, Qemu and 1 more 6 Debian Linux, Leap, Qemu and 3 more 2025-04-12 2.1 LOW 6.0 MEDIUM
The xhci_ring_fetch function in hw/usb/hcd-xhci.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 failure to limit the number of link Transfer Request Blocks (TRB) to process.
CVE-2016-3710 7 Canonical, Citrix, Debian and 4 more 15 Ubuntu Linux, Xenserver, Debian Linux and 12 more 2025-04-12 7.2 HIGH 8.8 HIGH
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.
CVE-2016-8669 4 Debian, Opensuse, Qemu and 1 more 6 Debian Linux, Leap, Qemu and 3 more 2025-04-12 2.1 LOW 6.0 MEDIUM
The serial_update_parameters function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving a value of divider greater than baud base.
CVE-2015-0235 7 Apple, Debian, Gnu and 4 more 18 Mac Os X, Debian Linux, Glibc and 15 more 2025-04-12 10.0 HIGH N/A
