  3. CVE-2024-53042
In the Linux kernel, the following vulnerability has been resolved: ipv4: ip_tunnel: Fix suspicious RCU usage warning in ip_tunnel_init_flow() There are code paths from which the function is called without holding the RCU read lock, resulting in a suspicious RCU usage warning [1]. Fix by using l3mdev_master_upper_ifindex_by_index() which will acquire the RCU read lock before calling l3mdev_master_upper_ifindex_by_index_rcu().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ipv4: ip_tunnel: Se corrige la advertencia de uso sospechoso de RCU en ip_tunnel_init_flow() Hay rutas de código desde las que se llama a la función sin mantener el bloqueo de lectura de RCU, lo que resulta en una advertencia de uso sospechoso de RCU [1]. Se soluciona utilizando l3mdev_master_upper_ifindex_by_index() que adquirirá el bloqueo de lectura de RCU antes de llamar a l3mdev_master_upper_ifindex_by_index_rcu().
