Description

A NULL pointer dereference was found in the libvirt API responsible introduced in upstream version 3.10.0, and fixed in libvirt 6.0.0, for fetching a storage pool based on its target path. In more detail, this flaw affects storage pools created without a target path such as network-based pools like gluster and RBD. Unprivileged users with a read-only connection could abuse this flaw to crash the libvirt daemon, resulting in a potential denial of service.

Affected products

• libvirt: from 3.10.0 before 6.0.0 — fixed in 6.0.0

How to fix

Upgrade to a fixed version: libvirt 6.0.0. Check the vendor advisory for mitigations.
