See https://bugs.launchpad.net/qemu/+bug/1886318 , in particular the #13 in there (the patch) - I applied this to qemu which crashes after revert-memory-accept-mismatching-sizes-in-memory_region_access_valid-CVE-2020-13754.patch when run as the device model for Xen HVM domU. Here's the output:
invalid size: acpi-cnt addr 0 size: 1 invalid size: acpi-cnt addr 0 size: 1 after this it just dies. This is another incarnation of LP#1886318 . What can we do here? Thanks, /mjt
