Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ksmbd: corrige desbordamientos de enteros en sistemas de 32 bits En sistemas de 32 bits, las operaciones de suma en ipc_msg_alloc() pueden potencialmente desbordarse y provocar daños en la memoria. Agregue la comprobación de los límites mediante KSMBD_IPC_MAX_PAYLOAD para evitar desbordamientos.
