This update for QEMU, a fast processor emulator, backports support to passthrough the pschange-mc-no CPU flag. The virtualised MSR seen by a guest is set to show the bug as fixed, allowing to disable iTLB Multihit mitigations in nested hypervisors (cf. DSA 4564-1).

For the stable distribution (buster), this problem has been fixed in version 1:3.1+dfsg-8+deb10u3.

We recommend that you upgrade your qemu packages.
