What is CVE-2019-18844?

The ACRN Hypervisor's Device Model prior to version 2019w25.5-140000p contains a vulnerability where reliance on assert calls for error propagation may allow an attacker to exploit the PCI core. This could result in denial of service due to assertion failures, compromising the stability of the hypervisor. Mitigations have been implemented in the subsequent updates, addressing the security oversight by enhancing error reporting mechanisms.
