Ars Technica reviews macOS 27 Golden Gate, highlighting an unavoidable Apple Intelligence upgrade, new AFM 3 Core models, and dropped Intel Mac support.

Apple Intelligence runs on a new AFM 3 Core model built in collaboration with Google, while the more capable AFM 3 Core Advanced requires an M3 chip and at least 12GB of RAM. The release drops all Intel Mac support, requiring Apple Silicon, with Sequoia security updates expected to end in fall 2027 and Tahoe's in 2028.

Researcher Chaotic Eclipse released HardBreacher, a PoC privilege-escalation exploit for Kaspersky Endpoint Security on fully patched Windows 11 25H2.
Security researcher Chaotic Eclipse, also known as INFINITE NIGHTMARE and Nightmare-Eclipse, released a PoC zero-day exploit named HardBreacher targeting Kaspersky Endpoint Security v14.0.0.504. The exploit achieves privilege escalation on fully patched Windows 11 25H2, creating a DLL in System32 with full user permissions and potentially disrupting Kaspersky's UI process and file-access controls. The PoC is unstable and may require repeated attempts; Kaspersky claims it has already addressed the vulnerability.
