[Global Network Technology Reporter Chen Jian] The recent explosion of Intel processor security flaws will affect hundreds of millions of devices. The Intel CEO stated that these vulnerabilities are not unique to Intel. Google Security Team Project Zero said that these vulnerabilities have affected almost all microprocessors on the market. AMD, ARM, or Intel's processors are hard to spare. ARM also confirmed that some of its chip architectures are affected. ARM confirmed 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. ARM has just released a latest security update. From the perspective of update support, several iPhone, iPad, iPod, and Apple TV products are likely to be affected. ARM also produced a chart for this, admitting that its Cortex-A8, -A9, -A15, -A17, -A57, -A72, -A73 and -A75 chips are vulnerable to more than two vulnerabilities. Over the past five years, chips including Apple and Samsung, Sony's game consoles and products using Qualcomm chips have all been affected. ARM Cortex technology has been widely licensed for use on different brands of chips. Therefore, the scope of this impact has been very wide, even Must be no less than the coverage of Intel chips. People always think that Apple can do its own thing. In fact, it is just self-anaesthetic of fruit powder. According to ARM's statement, including iPhone 4; iPhone 4S; iPhone 5; iPhone 5C; First-generation iPad; iPad 2; Third-generation iPad; Second-generation/third-generation Apple TV; Fourth-generation/fifth-generation iPod Touch Will be affected. Among them, 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. Apple's A4 processor uses the ARM Cortex-A8 core, which includes the first generation of the iPad, the iPhone 4, the fourth-generation iPod Touch, and the second-generation Apple TV. The A5 and A5X chips use the ARM Cortex-A9 core, which includes the iPad 2, the first-generation iPad Mini, the iPhone 4S, the third-generation Apple TV, and the fifth-generation iPod Touch. The third generation iPad uses the A5X chip. The A6 chip uses the ARM Cortex-A15 core and the models used include the iPhone 5 and the iPhone 5C. It is unclear whether Apple's own chips and customized Cortex chips will be affected. However, because Apple has adopted ARM's technology in large quantities, it is difficult to avoid chips such as A9. However, the existence of loopholes in the above devices has not been officially confirmed by Apple. In addition, many of the above devices have already been removed from the Apple Store. However, due to the relatively long life cycle of Apple devices, Apple will certainly be responsible for the safety of these users. Since the complete information of this chip-level vulnerability has not been disclosed, it is not ruled out that more iOS devices may be affected. At present, ARM has released security update packages for the Cortex A8, Cortex A9, and Cortex A15 processors. 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. ARM said that the vulnerability is very low. Due to the current use of this vulnerability, the attack method relies on locally running malware, so if you haven't escaped your Apple device, it's not easy. As for the other chip giant AMD's response, there are some contradictions. Intel issued a statement that CPU security vulnerabilities are not unique to its chips, suggesting that other chip makers such as ARM and AMD chips may also have such vulnerabilities. AMD began dismissing Intel’s statement on the recently recorded security breach on Wednesday. AMD engineers stated that only Intel’s chips were affected. The engineer also stated that AMD processors are not affected by this vulnerability because of concerns about performance degradation in AMD CPUs. It is recommended that users disable the new security features introduced in the Linux kernel to solve the problems caused by this vulnerability. At present, there are no cases where these two loopholes have been exploited. However, computer system risks have not yet erupted. However, due to chip loopholes that may affect all computer devices in the world, the wide range still raises people's heightened vigilance. Almost all PC and data center chips are provided by Intel and AMD, while ARM chips are used in most smart phones. Because vulnerabilities are related to hardware, different operating systems have to fix the vulnerability from the kernel level, which may reduce the performance of the processor by up to 30%. The consumer experience will certainly be greatly affected.
