CVE-2022-41739

Host access via container isolation escape

Published Apr 26, 2023 · Updated Jan 31, 2025

Container isolation failure in IBM Storage Scale Container Native Storage Access 5.1.2.1 through 5.1.6.0 allows local users to access the host. IBM has not disclosed the affected component or the operation that incorrectly permits a containerized program to cross the host isolation boundary. Reachability requires program execution inside a CNSA container; successful exploitation grants additional host capabilities or access to sensitive host information without a reported availability impact.
