  2. Vulnerabilities (CVE)
  3. CVE-2024-46681
In the Linux kernel, the following vulnerability has been resolved: pktgen: use cpus_read_lock() in pg_net_init() I have seen the WARN_ON(smp_processor_id() != cpu) firing in pktgen_thread_worker() during tests. We must use cpus_read_lock()/cpus_read_unlock() around the for_each_online_cpu(cpu) loop. While we are at it use WARN_ON_ONCE() to avoid a possible syslog flood.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pktgen: uso de cpus_read_lock() en pg_net_init() He visto que WARN_ON(smp_processor_id() != cpu) se activa en pktgen_thread_worker() durante las pruebas. Debemos usar cpus_read_lock()/cpus_read_unlock() alrededor del bucle for_each_online_cpu(cpu). Mientras estamos en ello, use WARN_ON_ONCE() para evitar una posible inundación de syslog.
