CVE-2026-33743

Description

A flaw was found in Incus, a system container and virtual machine manager. A user with access to Incus' storage bucket feature can exploit this vulnerability by using a specially crafted storage bucket backup. This can cause the Incus daemon to crash, leading to a denial of service of the control plane API. Repeated exploitation can keep the server offline, though existing containers and virtual machines will continue to operate.
