(Original headline: ARM confirms processor flaw impacts some Android, iOS, Nvidia, and Sony devices) Netease Technology News January 5, according to VentureBeat report, following the recognition of insecure memory leaks will affect millions of Intel processors, ARM confirmed today that many Cortex series processors also have loopholes. ARM's Cortex technology is used on a variety of Android and iOS devices, as well as some Nvidia Tegra products, Qualcomm Snapdragon chips, and Sony PlayStation Vita. After describing four different exploitable processor vulnerabilities, ARM released a chart admitting its Cortex-A8, -A9, -A15, -A17, -A57, -A72, -A73, and -A75 chips. Both are vulnerable to more than two vulnerabilities. The first three Cortex processors were used on older Apple iOS, Nvidia Tegra, Samsung Exynos devices, and Sony’s PlayStation Vita. They have also appeared on some Google-branded phones and other Qualcomm Snapdragon-enabled phones in the past five years. . Given that ARM Cortex technology is widely licensed for use on different brands of chips, the Cortex processors customized by individual manufacturers are affected to varying degrees, and compiling the list of detailed equipment affected by this is almost impossible. However, the Cortex-A8, -A9, and -A15 technologies are used in the first three iPads, the original iPad mini, the iPhone 4/4s/5/5c, the iPod touch 4G/5G, and the Apple TV 2G/3G. Nvidia's Tegra 2, 3, 4, and K1 also use ARM processors, as does Samsung's Exynos 3110, 4 and 5 chips. It is unclear whether Apple's A-series chip design has avoided these loopholes, including the custom Cortex chip and later Apple's internally developed processor. In fact, protecting ARM-based devices requires different methods based on specific chips and operating systems. ARM is instructing Android and "other operating system" users to look for patches from their device's operating system provider, while providing Linux with "software measures" for ARM development. Google has released patches for Android products, but other Android devices are waiting for vendor patches. Apple has not yet publicly stated which devices have been affected, nor has it published a shared solution. If iOS devices are affected, Apple may provide patches through software updates, but its performance impact is still unknown. Intel CEO Brian Krzanich said that many products will be affected, but the degree of influence will be different. Mobile phones, personal computers, etc. will be affected more or less, but will vary from product to product. ARM said that the risk of exploiting these vulnerabilities is low. It should be noted that this method of attack relies on locally running malware, which means that users must ensure security by keeping their software up-to-date and avoid clicking on suspicious links or downloading suspicious software.
