CVE-2026-68421

The CVE-2026-68421 entry concerns the Linux kernel sched_ext path. The issue arises when put_prev_task_scx() warns about a runnable task dropping to a lower sched_class without ENQ_LAST, due to core scheduling forcing idle via an SMT sibling’s core_pick path which bypasses balance_one(). The miti...
