AMD has released mitigation and firmware updates to address a high-severity vulnerability that can be exploited to load malicious CPU microcode on unpatched devices. [...]
More than six years after the Spectre security flaw impacting modern CPU processors came to light, new research has found that the latest AMD and Intel processors are still susceptible to speculative execution attacks
The latest generations of Intel processors, including Xeon chips, and AMD's older Zen 1, Zen 1+, and Zen 2 microarchitectures on Linux are vulnerable to new speculative execution attacks that bypass existing 'Spectre' mitigations. [...]
Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR)
With speculative execution attacks remaining a stubbornly persistent vulnerability ailing modern processors, new research has highlighted an "industry failure" to adopting mitigations released by AMD and Intel, posing a firmware supply chain threat
Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm and stage speculative execution attacks such as Spectre to leak sensitive information from host memory
