A security vulnerability that cannot be patched has been disclosed in Apple’s A12 and A13 chips, drawing renewed attention to the potential for jailbreaking and further hacking research on older iPhones. Barcelona-based offensive cybersecurity firm Paradigm Shift released the flaw, dubbed “usbliter8,” along with proof-of-concept code and technical analysis. The issue resides in the BootROM, which runs first at startup and cannot be fixed through software updates, though exploitation requires physical access.

TSMC, the world’s largest foundry, unveiled its semiconductor process roadmap through 2029, introducing next-generation A13, A12 and N2U processes. It adjusted parts of its existing plan, pushing A16 mass production to 2027 to match key customer product schedules. The company said A13 targets a 6 percent chip area reduction while keeping design rules, and N2U aims performance and power gains. TSMC also highlighted packaging technologies including CoWoS and SoW-X.
