TikTag — an attack on the speculative execution mechanism in ARM CPUs that allows bypassing MemTag protection
A group of researchers from Seoul University and Samsung has developed a technique called TikTag to attack ARM processors, which can be used to bypass the hardware protection mechanism MemTag (MTE, Memory Tagging Extension) present in chips based on the ARMv8.5-A architecture. The attack allows for determining the contents of TikTag tags for arbitrary memory addresses due to data leaks arising from speculative […]
