Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved. The issue occurs when a task is descheduling and is requeued on a CPU that is excluded from the cpus mask. This can trigger a warning, particularly on large machines early in the boot process. The problem arises from an optimization in the ttwu() function that queues a task on the wakelist without checking if the task is still allowed to run on that CPU. Tracing has confirmed that the task should have migrated properly, but a parallel wakeup from udev can cause the task to be queued on the old CPU, triggering the warning.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
