New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two addresses, which allows attackers to trigger an invalid memory copy operation.
