Vulnerability fixed in ARM, AMD and Intel processors

Researchers at VU Amsterdam have found a new variant of the Spectre vulnerability. The researchers have dubbed the attack Branch History Injection. Previous mitigation for Spectre v2 is not sufficient to fully fix the vulnerability, according to the researchers. According to the researchers, this...

New Exploit Bypasses Existing Spectre-V2 Mitigations in Intel, AMD, Arm CPUs

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. Attacks like Spectre are designed to bre...
