A U.S. District Judge has dismissed a class action lawsuit brought against Apple for its handling of the Meltdown and Spectre vulnerabilities in ARM-based processors, which the plaintiffs blamed for slowing down iPhones, iPads, and other products with A-series chips.
The case was dismissed for lack of standing, according to the ruling, obtained by AppleInsider. The plaintiffs pointed to JetStream and GeekBench 4 benchmarks as showing that iOS 11.2.2 caused more performance degradation than claimed in some of Apple’s own testing, and that this was backed up by the Department of Homeland Security’s Computer Emergency Readiness Team (CERT). Davila called their argument “premised on a self-serving and selective reading of [the] Defendant’s test results,” however.
The GeekBench 4 data indicated a “decrease in performance ‘in most areas’,” not all, Davila elaborated, adding that CERT’s data showed slowdowns were frequent but not universal.
“Even if the GeekBench 4 benchmark test results and CERT report are construed liberally in Plaintiffs’ favor, these reports only support an inference that some users, not most and certainly not all users, experienced slower performance in their iDevices,” the judge wrote.
Davila also pointed out that the plaintiffs weren’t forced to stop using their devices because of the hacking threat posed by the vulnerabilities, and that they didn’t offer facts to show their devices had become worth less than what they paid after performance hits.
Initially thought to be limited to Intel silicon, Meltdown and Spectre were found to affect all modern processors, including ARM-based chips like Apple’s A-series SoCs. Shortly after initial reports went live, Apple issued a statement confirming all Mac and iOS CPUs are impacted by the security flaw.
Apple began the process of mitigating Mac vulnerabilities in December 2017, while later software and security updates patched iOS devices in January 2018. Additional fixes for macOS High Sierra and older Mac operating systems were also pushed out in January 2018.
The suit was originally launched about a year ago, and charged that Apple had known about Meltdown and Spectre since June 2017. Apple only admitted that its chips had been susceptible in early January 2018, after having implemented the aforementioned patches.
