Intel Corp. said Thursday that by the end of the week it will have issued updates to security exploits made public Tuesday for 90% the chips introduced in the past five years. Intel stock is down 2.6% to $44.10 in early afternoon trading. The company said it had already introduced patches for the “majority” of its chips introduced within the past five years. “Intel continues to believe that the performance impact of these updates is highly workload-dependent and, for the average computer user, should not be significant and will be mitigated over time,” the company said in a statement. “While on some discrete workloads the performance impact from the software updates may initially be higher, additional post-deployment identification, testing and improvement of the software updates should mitigate that impact.” The company also said that operating system makers, cloud computing providers, and device makers are among the companies that have updated products and services already. The two securities vulnerabilities made public Tuesday affect most chip designs around the world and Intel has acknowledged that the vulnerabilities could affect systems designed in the past decade or more. Executives on a Wednesday call with investors said that they did not expect the vulnerabilities to have a material impact on the company and that they were unaware of the threat being actually exploited. Intel stock is up 21.5% in the past 12 months, as the S&P 500 index has gained 20%. The Dow Jones Industrial Average, of which Intel is a component, has gained 25% in the past 12 months.
