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.

CVE-2020-10717 QEMU: virtiofsd: guest may open maximum file descriptor to cause DoS
A potential DoS issue was found in the virtio-fs shared file system daemon (virtiofsd) implementation of the QEMU. Virtiofsd is meant to share a host file system directory with a guest via virtio-fs device. The said DoS may occur on the host, if the guest was to open the maximum number of file descriptors under the shared directory. A guest user/process may use this flaw to cause DoS issue on the host.
