Intel news: Massive security flaw detected in recent generations of CPUs

Major security flaws put virtually all phones & computers at risk

According to the investigators, the two vulnerabilities, dubbed Meltdown and Spectre, are present in all chips produced by Intel in the last 20 years, and are said to make the entire memory contents of computers accessible.

Intel shares fell nearly 2 per cent on Thursday as investors were worried about the potential financial liability and reputational damage from the recently disclosed security issues.

The flaws, called Spectre and Meltdown, potentially could enable hackers to extract protected data such as passwords and encryption keys. To fix the bug, Microsoft and other OS vendors need to redesign their kernels, this requires an OS-level overwrite of the kernel. This could come in the form of a more aggressive marketing tactic or better security features for their CPUs. This is a hole baked into the very chips' design. Through the exploit, attackers may gain access to data, though they do not have the power to modify or delete them, Intel added.

Intel also acknowledged that the patch will slow down its chips in some instances, but the slowdown will be workload-dependent.

Intel, Santa Clara, Calif., declined to comment on the lawsuits. The flaw leaves your personal devices vulnerable to attack.

Microsoft, Apple and Google have addressed the critical security bug with the December or January Update.

But Google had previously notified Intel of the vulnerability in June, according to Business Insider. Xbox and fully updated Windows 10 is safe.

Intel's CEO sold shares in his company several months after Google informed the chipmaker of a serious security problem affecting its products.

They also claimed they aren't the only ones affected and denied that a fault in their systems was to blame. Mike Ybarra, Xbox platform lead, tweeted that the security architecture of Xbox already includes mitigation against Meltdown and Spectre vulnerabilities.

In the case of some discrete workloads where the performance impact will initially be higher, Intel expects the impact to be reduced by additional post-deployment identification, testing and improvement of the software updates. This includes laptops, desktops, smartphones, and cloud servers.

Since the exact bug is under heavy embargo due to its nature, no other details are available. "It's not an issue with our product".
