CVE-2015-3780: The Bluetooth subsystem in Apple OS X before 10.10.5 allows attackers to obtain sensitive kernel memory-lay...

Security readout for executives and security teams

This is an old Apple OS X Bluetooth information disclosure issue. A crafted app could expose sensitive kernel memory-layout information, which may help bypass protections during a broader attack. The source bundle identifies OS X before 10.10.5 as affected and points to Apple’s 2015 security update. Exposure is most relevant to legacy Mac endpoints still running OS X before 10.10.5. The described attack path requires a crafted app, so systems that allow untrusted local applications are higher concern. Treat as a legacy endpoint hygiene issue unless pre-10.10.5 Macs remain in production. Prioritize upgrade or retirement for affected systems, especially where users can run untrusted apps. Mitigation focus: Upgrade affected OS X systems to 10.10.5 or later per Apple guidance.; Retire or isolate legacy Macs that cannot receive the Apple security update.; Restrict installation and execution of untrusted applications on remaining legacy systems..
