 "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched_ext: Replace SCX_RQ_BAL_KEEP with a dispatch verdict return\n\nSCX_RQ_BAL_KEEP tells the pick to keep running the previous task, a leftover\nfrom when balancing and picking were separate operations. An rq-level flag\nonly works while dispatches and picks pair up one to one, which core\nscheduling breaks: selections interleave through dispatch's lock drops and a\npick can consume a stale flag, keeping a task that has since been dequeued.\nFixing core scheduling support requires the decision to travel with the\ndispatch that made it. Make scx_dispatch_sched() and balance_one() return an\nexplicit verdict instead and drop the flag's plumbing from the tools autogen\nenum headers.\n\nAlso factor the pick-side invocation, its follow-up queueing and the\npost-dispatch checks out of do_pick_task_scx() into dispatch_pick(). No\nfunctional changes intended.\n\nv2: Drop the SCX_RQ_BAL_KEEP plumbing from the tools autogen enum headers\n    as well (Andrea).",
