CVE-2022-28228Network attack vector

Memory disclosure or crash via crafted INSERT

Published Dec 23, 2022 · Updated Apr 15, 2025

Out-of-bounds read in Yandex YDB before 22.4.44 allows remote attackers to disclose server memory or crash a database node. A crafted INSERT query causes the YDB server to read beyond its intended memory boundary; the vendor has not identified the affected parser or function. Network access to the query service is sufficient, with no authentication or user interaction required, and the bounded consequences are memory disclosure or a process crash.
