Vulnerability CVE-2019-18844
Published: 2019-11-13   Modified: 2019-11-14

Description:
The Device Model in ACRN before 2019w25.5-140000p relies on assert calls in devicemodel/hw/pci/core.c and devicemodel/include/pci_core.h (instead of other mechanisms for propagating error information or diagnostic information), which might allow attackers to cause a denial of service (assertion failure) within pci core.

Type:

CWE-617
