Google information security expert Tavis Ormandy discovered the Zenbleed vulnerability in AMD Ryzen processors that could allow attackers to steal sensitive user data, including passwords. In this respect informs Tom’s Hardware Portal.
Ormandy said that the Zenbleed vulnerability applies to all 2019-2020 devices based on the Zen 2 architecture, including AMD EPYC and Ryzen 3000, 4000 and 5000 processors.
Using Zenbleed, attackers can extract up to 30KB per second of information from each processor core. This bandwidth is enough to steal sensitive information processed by the processor. The vulnerability is operating system independent and cannot be bypassed through isolation or virtualization.
Ormandy told AMD about his discovery on May 15, but the company was unable to resolve the issue in time. The company has already released a fix for its EPYC 7002 Rome server processors, but the fix won’t be available for other Zen 2-based products until the end of the year.
PlayStation 5, Xbox Series and Steam Deck game consoles are also working on the Zen 2 architecture, but it is not known whether they are affected by this vulnerability.
The former Russians said about the WormGPT neural network, created specifically for hackers and scammers.
