AMD acknowledges CTS Labs exploits, will fix them in the next weeks
Last week, security research company CTS Labs reported its findings regarding 13 critical vulnerabilities that come with AMD’s Ryzen and EPYC processors, and demanded to get a response from AMD in just 1 day. CTS Labs also refused to provide details on each vulnerability, raising suspicions regarding the authenticity and the nature of its report. After more than one week, AMD is finally taking an official position with a blog post informing that all the issues reported by CTS Labs can and will be fixed in the coming weeks.
Here are the most important aspects presented in the AMD response post:
• The new exploits are not related to the Meltdown/Spectre vulnerabilities
• All 13 exploits can only be reproduced with admin access on the affected system
• The vulnerabilities are related to AMD’s Secure Processor firmware and its impact on some socket AM4 and TR4 desktop platforms
• Since the exploits have nothing to do with the microarchitecture itself, AMD will only release BIOS updates with firmware patches via OEMs and ODMs
• The fixes will not impact performance in any way and will be released in the coming weeks (90 days or less)
AMD had its share of troubles with the Meltdown/Spectre vulnerabilities and the consequent lawsuits, but it seems the company managed to tackle the CTS Labs debacle fairly well, as these new vulnerabilities are not hardware-related. However, AMD will most likely follow Intel’s footsteps by implementing hardware fixes for the Meltdown/Spectre vulnerabilities in its upcoming CPU models.
