CVE-2017-5715

CVE-2017-5715 (Spectre Variant 2) describes speculative-execution side-channel issues used to disclose memory. Connected docs show concrete mitigations and impact across vendors: AMD notes that LFENCE/JMP mitigation (V2-2) may be insufficient on some CPUs; AMD recommends standard mitigations (ret...

Spectre and Meltdown Attacks

After a week or so of rumors, everyone is now reporting about the Spectre and Meltdown attacks against pretty much every modern processor out there. These are side-channel attacks where one process can spy on other processes. They affect computers where an untrusted browser window can execute cod...
