Описание
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.

Отчет
Red Hat Enterprise Linux 5 and 6 are not affected by this issue as they shipped an older version of libvirt which did not include the vulnerable code. This flaw affects versions of the libvirt package as shipped with Red Hat Enterprise Linux 7 and 8 as well as Red Hat Enterprise Linux Advanced Virtualization 8. Future libvirt package updates for these products may address this issue.
