From an article by Jeff Foust in SpaceNews: 

WASHINGTON — As the crew of the International Space Station worked Aug. 30 to fix, at least temporarily, a minor air leak, the incident illustrated the growing orbital debris risk to the outpost and strains in American and Russian approaches to ISS operations.

NASA, in a statement early Aug. 30, said that controllers first noticed a minor drop in air pressure within the station at around 7 p.m. Eastern Aug. 29. Flight controllers allowed the crew to continue sleeping since the pressure drop did not pose an immediate risk to the crew, who were notified of the problem when they woke up at their regular time.

The station’s crew traced the drop in air pressure to a hole about two millimeters in diameter in the orbital module of the Soyuz MS-08 spacecraft docked to the station. They covered the hole with a piece of Kapton tape to slow the rate of the leak temporarily.
