All Raspberry Pi Devices Are Immune to the Meltdown and Spectre Vulnerabilities

Earlier this week, two major hardware bugs were unearthed in modern processors, affecting almost all devices powered by some CPUs from Intel, AMD, or ARM made in the past two decades. The Meltdown and Spectre vulnerabilities are considered the worst chip flaw ever discovered, putting billions of devices at risk of attacks. In a lengthy post published on Friday, Raspberry Pi Founder Eben Upton explains what the side-channel attack is and how speculative execution works on modern processors, claming that all Raspberry Pi models are immune to the Meltdown and Spectre security exploits as they use ARM1176, Cortex-A7, and Cortex-A53 processors.
