A group of academics from KU Leuven and the University of Birmingham has demonstrated a new vulnerability called Battering RAM to bypass the latest defenses on Intel and AMD cloud processors
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. [...]
Security researchers have uncovered yet another vulnerability affecting numerous older AMD and Intel microprocessors that could bypass current defenses and result in Spectre-based speculative-execution attacks
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
Security researchers have found new a new way to bypass existing hardware-based defenses for speculative execution in modern computer processors from Intel, AMD, and ARM. [...]
