CVE-2016-1922 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 2.1 LOW | 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-2016-9916 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2025-04-12 | 4.9 MEDIUM | 6.5 MEDIUM |
Memory leak in hw/9pfs/9p-proxy.c in QEMU (aka Quick Emulator) allows local privileged guest OS users to cause a denial of service (host memory consumption and possibly QEMU process crash) by leveraging a missing cleanup operation in the proxy backend. | |||||
CVE-2016-9846 | 1 Qemu | 1 Qemu | 2025-04-12 | 4.9 MEDIUM | 6.5 MEDIUM |
QEMU (aka Quick Emulator) built with the Virtio GPU Device emulator support is vulnerable to a memory leakage issue. It could occur while updating the cursor data in update_cursor_data_virgl. A guest user/process could use this flaw to leak host memory bytes, resulting in DoS for a host. | |||||
