The aircraft was forced to land using paper maps after its GPS signal was disrupted, the Financial Times reported, citing three officials familiar with the incident.
The European Commission confirmed on Monday that von der Leyen’s plane experienced GPS interference but said it landed safely, public broadcaster Polish Radio's IAR news agency reported.
Officials have previously accused Russia of jamming navigation signals along NATO’s eastern flank and disrupting air and sea traffic.
Poland's Prime Minister Donald Tusk warned last month that such disruptions could have serious consequences for critical infrastructure projects.
He said at the time that "such interference, most likely originating from Russia's Kaliningrad region, is disrupting air traffic, including passenger flights, and now also threatens the precision of strategic investment projects."
Tusk told reporters that GPS signal jamming had been reported by pilots from Poland, Sweden, Estonia and Lithuania since Russia’s full-scale invasion of Ukraine.
In July, the International Civil Aviation Organization (ICAO) called on Russia to cease GPS interference in the region after reviewing evidence submitted by Poland, Finland, Sweden, and the Baltic states, Polish state news agency PAP reported.
The disruptions have forced aircraft, ships and drones to alter their routes, it said.
