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".
