- 主题:amd的meltdown来了
怎么办，急急急
Update, 8/31/2021 7:30am PT: Updated article and title to clarify that the vulnerability applies to all AMD processors, not just the Zen 2 and Zen+ models listed in the research paper.
Original article:
According to security researchers and AMD, the company's Zen 2 and Zen+ processors suffer from a new Meltdown-like vulnerability, but the problem appears to be far more wide-ranging. AMD has prepared a guide on mitigating the vulnerability and published details about how the vulnerability works, but the company's security bulletin also notes that all AMD CPUs are vulnerable. Called "Transient Execution of Non-canonical Accesses," this vulnerability acts very similarly to the already-disclosed Meltdown vulnerability that only impacts Intel CPUs.

Should you be worried? Probably not. In the whitepaper, the researchers did note that "AMD's design decisions indeed limit the exploitability scope" when compared to Meltdown-style attack vectors affecting Intel's CPUs, "yet it may be possible to use them to amplify other microarchitectural attacks."
Additionally, AMD's mitigation is for software vendors to review their code for any possible security holes related to this, adding that "potential vulnerabilities can be addressed by inserting an LFENCE or using existing speculation mitigation techniques."
On the user side of things, it sounds like the best thing to be done is to stay up to date with the latest patches.

我靠，射射发抖，这要缩杠了啊？我很有理由怀疑，AMD在使坏，故意在新U要发布时机给老U打补丁
