CVE-2016-9913

CVE-2016-9913 affects QEMU’s 9pfs backend (hw/9pfs/9p.c) where a memory leak in v9fs_device_unrealize_common can be triggered by the order of resource cleanup. This local privilege-adjacent issue may cause host memory consumption and potentially crash the QEMU process. The vulnerability is discus...

CVE-2016-2197

QEMU (with IDE AHCI emulation) is affected by CVE-2016-2197 due to a NULL pointer dereference when unmapping FIS and CLB entries, allowing a privileged guest user to crash the QEMU process and cause a DoS. Remediation per sources includes upgrading to a fixed release (PowerKVM advisory notes this...

CVE-2015-8745

CVE-2015-8745 affects QEMU with VMXNET3 paravirtual NIC emulation. Issue: reading Interrupt Mask Registers (IMR) can crash the QEMU process when exploited by a privileged guest (CAP_SYS_RAWIO), causing DoS. Connected data confirms the crash is tied to IMR access, not a remote exploit, and multipl...

CVE-2016-1922

CVE-2016-1922 : QEMU built with the TPR optimization for 32-bit Windows guests is vulnerable to a NULL pointer dereference during I/O port write operations via the hmp interface , where the current_cpu may be null. This can crash the QEMU instance, causing a DoS. No patch/version details are prov...

CVE-2015-8818

CVE-2015-8818 (QEMU) affects the CPU path in QEMU where cpu_physical_memory_write_rom_internal in exec.c fails to skip MMIO regions, allowing a local privileged guest user to crash the guest (DoS) via unspecified vectors. Public details confirm the issue and multiple advisories reference fixes; r...

CVE-2016-1981

CVE-2016-1981 affects QEMU built with the e1000 NIC emulation. The issue is an infinite loop that can occur while processing data via transmit or receive descriptors when the initial TDH/RDH is outside the allocated descriptor buffer. A privileged user inside the guest could crash the QEMU instan...

CVE-2015-8743

CVE-2015-8743 affects QEMU with NE2000 device emulation. The flaw is an out-of-bounds read/write in ioport r/w operations, exploitable by a privileged (CAP_SYS_RAWIO) user to leak or corrupt QEMU memory. Public fixes exist (e.g., vendor security updates, notably in SUSE/OpenSUSE advisories) that ...

CVE-2016-9846

CVE-2016-9846 affects QEMU with Virtio GPU device emulation. The vulnerability is a memory leakage in virgl cursor data update (update_cursor_data_virgl), which could allow a guest user/process to leak host memory, causing a host DoS. Connected advisories (Ubuntu USN-3261-1, Fedora/Fedora-derived...

CVE-2015-8744

CVE-2015-8744 affects QEMU when built with a VMXNET3 paravirtual NIC; the issue arises from improper/layer-2 header handling for very small frames (less than 22 bytes), which could be exploited by a privileged guest to crash the QEMU process and cause DoS. Public details in Debian/related advisor...

CVE-2016-9776

CVE-2016-9776 affects QEMU’s ColdFire Fast Ethernet Controller (mcf_fec_receive) and can trigger an infinite loop when processing received packets. This could allow a privileged guest user to crash the QEMU host process, causing a Denial of Service. Public advisories for related products (PowerKV...

CVE-2016-2198

CVE-2016-2198 affects QEMU when built with USB EHCI emulation. The root cause is a null pointer dereference in ehci_caps_write during writes to EHCI capability registers, which could be triggered by a privileged user inside the guest and may crash the QEMU process, causing a DoS. Technical detail...

CVE-2016-1981

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...

CVE-2015-8817

QEMU aka Quick Emulator built to use 'addressspacetranslate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pcidmaread/write calls.
