A flaw was found in BuildKit. This vulnerability allows an authenticated user to cause a Denial of Service (DoS) by crashing the daemon. When the BuildKit daemon is started with Container Device Interface (CDI) support disabled, submitting a build that attempts to use CDI devices triggers an unhandled daemon panic.

Description OSIDB Bzimport 2026-10-05 17:53:48 UTC
If BuildKit daemon is started with --cdi-disabled it can lead to daemon panic when builds try to use CDI devices. This can happen maliciously or by accident.
