AI-analyzed exploit summary This repository contains a proof-of-concept exploit for CVE-2020-25637, a double-free vulnerability in libvirt versions prior to 6.8.0. The exploit demonstrates how to trigger the vulnerability by querying network interface information of a QEMU domain, potentially leading to a denial of service or privilege escalation.
Description
A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
