Security researchers say Specter vulnerability Intel and arm He said that it started to pose a danger to its processors again. However, the new report shared by Intel is now AMD its users too Specter V2 (Spectre-BHB) says it could be a victim of vulnerability.
New vulnerability affecting Intel and ARM processors Specter-BHB It has spread to AMD models. Intel’s IPAS STORM According to the report submitted by the security team, the update that AMD used to fix the Specter v2 vulnerabilities has been ineffective since 2018. Intel claimed that AMD’s vulnerability updates were both inaccurate and ineffective.
New vulnerability for Intel: Millions of users are in danger!
A new type of Specter vulnerability has begun to affect Intel and Arm devices. Here is the critical danger that concerns millions.
Specter vulnerability risk for AMD users
To remind you Specter vulnerabilitieswas detailed by the research group VUSec, which collaborated with Intel the other day. The new Specter, which managed to infiltrate the processor to run the unauthorized code sequence as a security measure; It was affecting Intel 12th Gen (Alder Lake) and ARM processors. However, AMD also seems to have had its share of this vulnerability.
AMD was first Specter vulnerabilities suggested using an alternative method to mitigate its impact, but probably realized that previous updates had been ineffective. New research by IPAS STORM revealed that the update “CVE-2017-5715” offered by AMD is still insufficient for the Specter V2 vulnerability.
Working on alternative techniques to counter the impact of Specter V2, Intel discovered that the updates AMD has been using since 2018 to fix Specter vulnerabilities were not effective. AMD specifically relied on the “LFENCE/JMP” code sequence, but Intel Specter v2 attacks He said it wasn’t enough to stop him.
When it was first discovered by researchers Specter-BHB BHI stands for Branch History Injection. According to the researchers’ report, there is a proof-of-concept vulnerability to infiltrate the core memory of processors with BHI.
Earlier work released from 2013 of all Intel processors He said that he might be affected by this danger. on the arm side Cortex A15, A57, A72 and Neoverse V1, N1 and N2 There was danger to their cores. It is unclear for now which AMD processors are at risk.
