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-2016-8909 4 Debian, Opensuse, Qemu and 1 more 6 Debian Linux, Leap, Qemu and 3 more 2025-04-12 6.0 Medium
The intel_hda_xfer function in hw/audio/intel-hda.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via an entry with the same value for buffer length and pointer position.
CVE-2016-9776 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-12 5.5 Medium
QEMU (aka Quick Emulator) built with the ColdFire Fast Ethernet Controller emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could use this issue to crash the QEMU process on the host leading to DoS.
