CVE-2026-23294

The CVE describes a race in the Linux kernel’s PREEMPT_RT path for the per-CPU xdp_dev_bulk_queue (bq). The vulnerability arises because bq_enqueue() and __dev_flush() were believed to run atomically on the same CPU, but PREEMPT_RT can preempt, leading to concurrent access to bq->count and bq-...
