For the stable distribution (buster), this problem has been fixed in version 1:3.1+dfsg-8+deb10u7. In addition this update fixes a regression caused by the patch for CVE-2020-13754, which could lead to startup failures in some Xen setups.

We recommend that you upgrade your qemu packages.

For the detailed security status of qemu please refer to its security tracker page at: [link moved to references]");
