TITLE

ACRN Reachable vulnerability in reachable

Trust: 0.8

sources: JVNDB: JVNDB-2019-012159

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. This is fixed in 1.2. 6199e653418e is a mitigation for pre-1.1 versions, whereas 2b3dedfb9ba1 is a mitigation for 1.1. ACRN Contains a vulnerability with reachable assertions.Service operation interruption (DoS) There is a possibility of being put into a state. ACRN is an open source virtual machine monitor for the Internet of Things. There are security vulnerabilities in the previous version of ACRN 2019w25.5-140000p. An attacker can use this vulnerability to cause a denial of service
