Loading vulnerability…
CVE-2025-38234 is a race condition in the Linux kernel real-time scheduler's push_rt_task function. When find_lock_lowest_rq cannot immediately lock both the source and destination CPU runqueues, it may release the current runqueue lock before reacquiring both locks. During this interval, the selected task can migrate, execute, and be requeued by a concurrent wake-up operation. If the task is queued with on_rq equal to 1 and has run on the same CPU, existing checks can incorrectly accept it despite its removal from the pushable tasks list. The resulting inconsistent scheduler state can cause queue corruption and kernel panics.

A race condition in the Linux kernel real-time scheduler's push_rt_task function can incorrectly handle a task that migrates and is requeued while runqueue locks are temporarily released. This can corrupt scheduler queues and cause kernel panics, affecting availability. The advisory assigns a CVSS v3 base score of 4.7, with local access, high attack complexity, and low privileges required.
A race condition in the Linux kernel real-time scheduler's push_rt_task handling allows a task to migrate, execute, and be requeued while runqueue locks are temporarily released. Existing checks can incorrectly accept the task even though it is no longer in the pushable-task list, resulting in scheduler corruption and kernel panics. The reference assigns CVSS v3 severity 4.7, indicating local access, high attack complexity, low privileges, and high availability impact without confidentiality or integrity impact.
