Eranga was reported during the second Test against England at Chester-le-Street in May 2016 and was barred from bowling in international matches when his action was found to be illegal following an independent assessment.
"Eranga underwent a re-assessment of his bowling action... with the assessment concluding that the amount of elbow extension in his standard deliveries was within the 15-degree level of tolerance permitted," the governing body said.
Eranga's ban was announced a few hours after he was taken to hospital for heart tests when he reported feeling discomfort while batting during a one-day international against Ireland.
