Intel has paid out a $100,000 bug bounty for new processor vulnerabilities that are related to Spectre variant one (CVE-2017-5753).
The new Spectre-class variants are tracked as Spectre 1.1 (CVE-2018-3693) and Spectre 1.2, of which Spectre 1.1 described as a bounds-check bypass store attack has been considered as more dangerous.
Earlier this year, Google Project Zero researchers disclosed details of Variants 1 and 2(CVE-2017-5753 and CVE-2017-5715), known as Spectre, and Variant 3 (CVE-2017-5754), known as Meltdown.
Spectre flaws take advantage of speculative execution, an optimization technique used by modern CPUs, to potentially expose sensitive data through a side channel by observing the system.
