HOMARD: Power-rail side channel recovers DRAM data on ARM SoCs

Mon, 12 Oct 2026 21:14:27 +0000

Engineer — Learn: Novel attack class: unprivileged power-telemetry sensors can reverse-engineer DRAM addressing and recover secret bytes without timing, bypassing existing timer-based mitigations. No patch exists; relevant if you run sensitive workloads on ARM SoCs (Jetson, Pi-class boards) where power rail access is attacker-accessible.
