CVE-2024-57900

In the Linux kernel, the following vulnerability has been resolved: ila: serialize calls to nf_register_net_hooks() syzbot found a race in ila_add_mapping() [1] commit 031ae72825ce ("ila: call nf_unregister_net_hooks() sooner") attempted to fix a similar issue. Looking at the syzbot repro, we have concurrent ILA_CMD_ADD commands. Add a mutex to make sure at most one thread is calling nf_register_net_hooks().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ila: serializar llamadas a nf_register_net_hooks() syzbot encontró una carrera en ila_add_mapping() [1] la confirmación 031ae72825ce ("ila: llamar a nf_unregister_net_hooks() antes") intentó solucionar un problema similar. Al observar la reproducción de syzbot, tenemos comandos ILA_CMD_ADD simultáneos. Agregue un mutex para asegurarse de que, como máximo, un hilo esté llamando a nf_register_net_hooks().
