Researchers have disclosed KernelSnitch, a novel side-channel attack exploiting timing variances in Linux kernel data structures, achieving covert data transmission rates up to 580 kbit/s and enabling website fingerprinting with 89% accuracy. The attack targets four critical container types: fixed/dynamic hash tables, radix trees, and red-black trees, bypassing hardware-based defenses through software-induced timing leaks. KernelSnitch […]
