Intel is responding to claims that the company’s processors have a security bug, and software fixes could slow down PCs. Reports this week have suggested that a security flaw in Intel processors, and allegedly not AMD ones, has led to a redesign of Linux and Windows kernels to protect against a hardware flaw. “Recent reports that these exploits are caused by a 'bug' or a 'flaw' and are unique to Intel products are incorrect,” says a statement from Intel. “Based on the analysis to date, many types of computing devices — with many different vendors’ processors and operating systems — are susceptible to these exploits.”

Intel says it’s working with AMD and ARM in a strongly worded statement, despite AMD engineer Tom Lendacky previously saying “AMD processors are not subject to the types of attacks that the kernel page table isolation feature protects against.” Intel says it planned to disclose this issue next week along with other vendors, but that it’s issuing a statement today due to what it angrily describes as “inaccurate media reports.”

Some reports suggested that the software and firmware fixes would cause performance slowdowns on PCs, and Intel doesn’t deny that. “Any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time,” says an Intel spokesperson. Intel does not address the obvious impact to server machines, though.

Intel is recommending that end users should “check with your operating system vendor or system manufacturer and apply any available updates as soon as they are available.” Here’s Intel’s statement in full:
