CVE-2026-33542

Incus does not verify combined fingerprint when downloading images from simplestreams servers PUBLISHED

Description (CNA)

Incus is a system container and virtual machine manager. Prior to version 6.23.0, a lack of validation of the image fingerprint when downloading from simplestreams image servers opens the door to image cache poisoning and under very narrow circumstances exposes other tenants to running attacker controlled images rather than the expected one. Version 6.23.0 patches the issue.
