Recharge disruption via unchecked slice access
Published Aug 27, 2026 · Updated Aug 27, 2026
Denial of service in free5GC 4.0.1 allows remote attackers to disrupt CHF recharge handling through a malformed recharging path. RechargePut splits rechargingInfo on underscores and reads element 1 without checking the slice length, causing an index-out-of-range panic. Network access to the CHF endpoint is required, while authentication requirements are undisclosed; Gin recovery returned HTTP 500 rather than a proven process crash.
