Google details CPU flaws, claims AMD, ARM and Intel all affected

Google Project Zero disclosed two widespread CPU side-channel vulnerabilities, Meltdown and Spectre, which exploit speculative execution to read privileged system memory. The report notes affected vendors (Intel, AMD, ARM), demonstrates proofs-of-concept that can read kernel memory, highlights particular risk to cloud multi-tenant systems, and cites mitigations such as KAISER/KPTI and operating system patches.
