Security readout for executives and security teams
This vulnerability affects Apple OS X before 10.11.5. A person with physical access to a locked Mac could reset an expired password because Screen Lock mishandled password profiles. The issue is important for legacy or managed Macs, but the sources do not show remote exploitation or active exploitation. Exposure is limited to Apple OS X systems before 10.11.5, especially devices using password expiration or password profile policies. Systems already updated to 10.11.5 or later are not indicated as affected by the supplied description. Treat this as a legacy endpoint hygiene issue with physical-access risk. It should be prioritized where older Macs remain in offices, shared workspaces, labs, or managed fleets with password expiration policies. Mitigation focus: Update affected OS X systems to 10.11.5 or later per Apple guidance.; Identify and retire unsupported legacy Mac systems where updates are unavailable.; Review MDM password profile policies on managed Macs..
