CVE-2017-7377 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 6.0 Medium
The (1) v9fs_create and (2) v9fs_lcreate functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS privileged users to cause a denial of service (file descriptor or memory consumption) via vectors related to an already in-use fid.
CVE-2017-7493 2 Debian, Qemu 2 Debian Linux, Qemu 2025-04-20 7.8 High
Quick Emulator (Qemu) built with the VirtFS, host directory sharing via Plan 9 File System(9pfs) support, is vulnerable to an improper access control issue. It could occur while accessing virtfs metadata files in mapped-file security mode. A guest user could use this flaw to escalate their privileges inside guest.
CVE-2022-4172 3 Fedoraproject, Qemu, Redhat 3 Fedora, Qemu, Enterprise Linux 2025-04-14 6.5 Medium
An integer overflow and buffer overflow issues were found in the ACPI Error Record Serialization Table (ERST) device of QEMU in the read_erst_record() and write_erst_record() functions. Both issues may allow the guest to overrun the host buffer allocated for the ERST memory device. A malicious guest could use these flaws to crash the QEMU process on the host.
CVE-2022-4144 3 Fedoraproject, Qemu, Redhat 5 Extra Packages For Enterprise Linux, Fedora, Qemu and 2 more 2025-04-14 6.5 Medium
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.
CVE-2016-9907 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-12 6.5 Medium
Quick Emulator (Qemu) built with the USB redirector usb-guest support is vulnerable to a memory leakage flaw. It could occur while destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host.
CVE-2016-9908 1 Qemu 1 Qemu 2025-04-12 3.3 Low
Quick Emulator (Qemu) built with the Virtio GPU Device emulator support is vulnerable to an information leakage issue. It could occur while processing 'VIRTIO_GPU_CMD_GET_CAPSET' command. A guest user/process could use this flaw to leak contents of the host memory bytes.
CVE-2016-9845 1 Qemu 1 Qemu 2025-04-12 6.5 Medium
QEMU (aka Quick Emulator) built with the Virtio GPU Device emulator support is vulnerable to an information leakage issue. It could occur while processing 'VIRTIO_GPU_CMD_GET_CAPSET_INFO' command. A guest user/process could use this flaw to leak contents of the host memory bytes.
CVE-2016-9846 1 Qemu 1 Qemu 2025-04-12 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.
