Tech firms are working to fix two bugs that could allow hackers to steal personal data from computer systems.
Google researchers said one of the “serious security flaws”, dubbed “Spectre”, was found in chips made by Intel, AMD and ARM.
The other, known as “Meltdown” affects Intel-made chips alone.
The industry has been aware of the problem for months and hoped to solve it before details were made public.
The UK’s National Cyber Security Centre (NCSC) said there was no evidence that the vulnerability had been exploited.
