AMD has issued patches against Masterkey, Fallout and Chimera vulnerabilities

AMD has provided patches to its partners for vulnerabilities that security firm CTS Labs disclosed last month. The chip designer reports that the updates for Epyc chips, among others, are in the final phase of testing.

CTS Labs pointed out to Tom’s Hardware that AMD hadn’t released any more information about the patches after the chip company announced it was working on them at the end of March. According to the security company, it would take months to close the vulnerabilities. One of them, Chimera, would even require a hardware change.

However, AMD reports to Tom’s Hardware that it has provided patches to its “ecosystem partners” about a month after CTS Labs’ notification. This concerns all vulnerabilities that affect the Epyc processors in addition to the Ryzen and Ryzen Pro processors affected by Chimera. These patches will appear after the final tests by partners.

The one for Ryzenfall, which involved the Ryzen chips, AMD expects to provide to partners this month. They can then validate this, after which the release can take place. CTS Labs announced the Ryzenfall, Fallout, Masterkey, and Chimera vulnerabilities in March. The publication has come under criticism for the company for providing AMD only 24 hours notice and appearing to exaggerate the impact, as administrator privileges are required to exploit the leaks. CTS Labs felt it was acting responsibly.
