Chipmaker AMD says its chips are susceptible to the speculative execution flaws in microprocessors known as Spectre. The flaws were first announced publicly on Jan 3 by Google Project Zero researchers, who last June shared vulnerability details with affected chipmakers Intel, AMD and ARM. Microsoft has warned that operating system fixes to address Spectre are slowing down systems, especially with older processors. AMD says it will be releasing “microcode” – firmware – updates and is working with operating system vendors to issue OS patches which together should mitigate the flaw.”]
