In the Linux kernel, the following vulnerability has been resolved: net: annotate data-races around sk->sk_{data_ready,write_space} skmsg (and probably other layers) are changing these pointers while other cpus might read them concurrently. Add corresponding READ_ONCE()/WRITE_ONCE() annotations for UDP, TCP and AF_UNIX.
En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: net: anotar condiciones de carrera de datos alrededor de sk->sk_{data_ready,write_space} skmsg (y probablemente otras capas) están cambiando estos punteros mientras otras CPUs podrían leerlos concurrentemente. Añadir las correspondientes anotaciones READ_ONCE()/WRITE_ONCE() para UDP, TCP y AF_UNIX.
