  3. CVE-2024-40993
In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Fix suspicious rcu_dereference_protected() When destroying all sets, we are either in pernet exit phase or are executing a "destroy all sets command" from userspace. The latter was taken into account in ip_set_dereference() (nfnetlink mutex is held), but the former was not. The patch adds the required check to rcu_dereference_protected() in ip_set_dereference().

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: ipset: corrige rcu_dereference_protected() sospechoso Al destruir todos los conjuntos, estamos en la fase de salida de pernet o estamos ejecutando un "comando de destruir todos los conjuntos" desde el espacio de usuario. Este último se tuvo en cuenta en ip_set_dereference() (se mantiene el mutex de nfnetlink), pero el primero no. El parche agrega la verificación requerida a rcu_dereference_protected() en ip_set_dereference().
