Security readout for executives and security teams
This OpenBSD 6.6 issue lets a local user bypass intended login-class restrictions through a flaw in su. It is not described as remote code execution, but it can weaken policy controls that separate user privileges, resource limits, or operational roles. Exposure appears limited to OpenBSD 6.6 systems with local user access and meaningful login-class policy controls. The bundle does not identify other affected products or versions. Prioritize remediation on OpenBSD 6.6 systems with shared local accounts, administrative users, or security-sensitive login classes. Risk is lower for systems without untrusted local users. Mitigation focus: Apply the OpenBSD 6.6 errata or current vendor-recommended fixes.; Upgrade unsupported OpenBSD 6.6 systems where feasible.; Review login classes for elevated capabilities or sensitive resource limits..
