| CVE-2020-10717 | 1 Qemu | 1 Qemu | 2021-12-20 | 2.1 LOW | 6.5 MEDIUM |
| A potential DoS flaw was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU version >= v5.0. Virtio-fs is meant to share a host file system directory with a guest via virtio-fs device. If the guest opens the maximum number of file descriptors under the shared directory, a denial of service may occur. This flaw allows a guest user/process to cause this denial of service on the host. | |||||

| hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash. | |||||
| CVE-2021-20221 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2021-12-10 | 2.1 LOW | 6.0 MEDIUM |
| An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said issue while updating controller state fields and their subsequent processing. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario. | |||||

| CVE-2021-3527 | 3 Debian, Qemu, Redhat | 3 Debian Linux, Qemu, Enterprise Linux | 2021-11-15 | 2.1 LOW | 5.5 MEDIUM |
| A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service. | |||||
