Cyber-security researchers have a new vulnerability to a wide swath of modern Computer chips and with the Spectre and core melt chip error, emerged in January.

The latest chip problem, known as the Speculative Saving Bypass or “variant 4”, because it was communicated in the same family as the original group of the defects, the security experts at Microsoft Corp’s (MSFT.O) and Alphabet Inc (GOOGL.O) Google on Monday. Although the vulnerability affects a number of chips from Intel Corp(INTC.O), Advanced Micro Devices, Inc. (AMD.O) and the Softbank group (9984.T) ARM Holdings, researchers described the risk as low, partly because of the web browser patches already issued, earlier this year, address Spectre.

The meltdown and the Spectre of error, the permit itself can be in January, passwords and other sensitive data to be read on the chips. The errors result from the way computers try to guess what the user is likely to happen next, a process known as speculative execution.

If the error was created in February, researchers warned that you will find likely to be new variants of Spectre in the future. Earlier this month, German computer science magazine c’t reports that a “next-generation” – the bug was found in Intel chips, and was likely to be disclosed this month. Intel declined to comment on whether Monday’s announcement was in connection with the German magazine ‘ history.

In his research, results, Microsoft said patches issued for popular web browsers increases earlier this year, the difficulty of performing the attack with the newly discovered errors.

The Chips from Intel, AMD, and ARM all have patches available, either directly from the producers and / or the software suppliers such as Microsoft. Intel said it expected a drop in performance between 2 percent and 8 percent of the patches, ARM-and said it expected a slowdown in the rate between 1 percent and 2 percent.

However, Intel said, because of the low risk of a real attack, the ship would be disabled its patches by default, so the user the choice of whether they. AMD also advised to leave disabled the patches, due to the difficulties in the implementation of an attack.

The security does not seem to be affected to have problems chip manufacturers’ share prices. Intel shares by nearly 16 percent, since the beginning of the year, to $54.32, and AMD shares are up 18.3 percent, to $12.99 since the beginning of the year.
