  "cwe" : "CWE-772",
  "details" : [ "A flaw was found in the Linux kernel's `sched_ext` component. The scheduler's direct dispatch state (`ddsp_dsq_id`) was not consistently cleared across all execution paths. This oversight could leave the system in an incorrect state, leading to spurious warnings and unexpected behavior during task dispatch. Such inconsistencies can contribute to overall system instability." ],
