Vulnerability Details CVEID: CVE-2018-3639 DESCRIPTION: Multiple Intel CPU''s could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to bypass security restrictions and gain read access to privileged memory. Note: This vulnerability is the Speculative Store Bypass (SSB), also known as Variant 4 or "SpectreNG".
