  "description": "In the Linux kernel, the following vulnerability has been resolved:  sched_ext: Wait for SCX_OPSS_DISPATCHING before reenqueueing a task  ebf1ccff79c4 (\u0022sched_ext: Fix ops.dequeue() semantics\u0022) moved the final ops_state store in scx_dispatch_enqueue() after the DSQ unlock so that the custody update and ops.dequeue() precede it. A task can thus be found on a DSQ while still SCX_OPSS_DISPATCHING.  The dequeue and core-sched pick paths wait for the state to clear in ops_dequeue() but the reenqueue paths don\u0027t. A reenqueue in that window runs ops.enqueue() and sets SCX_OPSS_QUEUED before the dispatch has completed. The dispatcher\u0027s final store then overwrites it with SCX_OPSS_NONE and finish_dispatch() drops every later dispatch of the task.  Wait for SCX_OPSS_DISPATCHING to clear before dequeueing a task for reenqueue, the same way ops_dequeue() does.",
