CVE-2019-18844: Linux Acrn

High severity, CVSS 7.5. EPSS: 1.7% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Acrn: before 2019w25.5-140000p (fixed in 2019w25.5-140000p)
