A new speculative execution attack named "TIKTAG" targets ARM's Memory Tagging Extension (MTE) to leak data with over a 95% chance of success, allowing hackers to bypass the security feature.

Arm was charging roughly the same royalty on a chip that appeared in a blender as one that went into a high-end data centre, which he says was “crazy”.

To tackle this issue, Apple researchers have developed a novel technique that uses flash memory – the same memory where your apps and photos live – to store the AI model's data.
