CVE-2024-46681

The CVE-2024-46681 entry affects the Linux kernel pktgen path: within pktgen_pg_net_init, the for_each_online_cpu loop was executed without holding a cpus_read_lock, risking a race that could trigger WARN_ON(smp_processor_id() != cpu) and flood logs. The fix introduces cpus_read_lock()/cpus_read_...
