Описание
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.
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.
Отчет
A denial of service flaw was found in BuildKit's device management subsystem when processing Container Device Interface (CDI) configurations. When the BuildKit daemon is explicitly started with CDI disabled via the --cdi-disabled flag, requesting a CDI device during a build triggers an unhandled panic due to an uninitialized device handler. An authenticated user authorized to submit build requests can crash the shared buildkitd daemon process, terminating running tasks and preventing subsequent build operations until the daemon restarts.
Меры по смягчению последствий
Avoid starting the BuildKit daemon with the --cdi-disabled flag, or restrict build submission access to trusted users to prevent deliberate or accidental daemon panics.
