CVE-2022-36125Network attack vector

Application crash via corrupted-data integer overflow

Published Aug 9, 2022 · Updated Mar 6, 2026

Integer overflow in Apache Avro Rust SDK before 0.14.0 allows remote attackers to crash applications with corrupted Avro data. The vendor advisory identifies overflow during corrupted-data reads but does not disclose the affected function or arithmetic operation. An application must pass attacker-supplied Avro data to the Rust SDK; exploitation produces a panic and service interruption, with no reported data disclosure or modification.
