hw/net/vmxnet3.c in QEMU 2.0.0-rc0, 1.7.1, and earlier allows local guest users to cause a denial of service or possibly execute arbitrary code via vectors related to (1) RX or (2) TX queue numbers or (3) interrupt indices. NOTE: some of these details are obtained from third party information.
CVE-2013-4529 1 Qemu 1 Qemu 2025-04-12 7.5 HIGH N/A
Buffer overflow in hw/pci/pcie_aer.c in QEMU before 1.7.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large log_num value in a savevm image.
CVE-2016-9912 1 Qemu 1 Qemu 2025-04-12 4.9 MEDIUM 6.5 MEDIUM
Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while destroying gpu resource object in 'virtio_gpu_resource_destroy'. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host.
CVE-2016-5105 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2025-04-12 1.9 LOW 4.4 MEDIUM
The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, uses an uninitialized variable, which allows local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command.
