Cybersecurity researchers have found a new security flaw that affects a broad swath of modern computing chips and is related to the Spectre and Meltdown chip flaws that emerged in January.
The newest chip problem, known as Speculative Store Bypass or “Variant 4” because it's in the same family as the original group of flaws, was disclosed by security researchers at Microsoft Corp and Alphabet Inc's Google on Monday. Though the flaw affects many chips from Intel Corp, Advanced Micro Devices Inc and Softbank Group's ARM Holdings, researchers described the risks as low, partly because of web browser patches already issued earlier this year to address Spectre.
