 CPU Security Flaw Spectre

The global microchip flaw which leaves computers and phone vulnerable to hackers is much worse than first feared, affecting potentially billions of devices. Researchers discovered the 'Meltdown' and 'Spectre' bugs have now revealed the full extent of the issue after reports first emerged that computers running Intel chips could have their passwords and other data stolen.

The second of the two bugs, Spectre, affects chips designed by Arm Holdings, the British company whose designs are used in almost all smartphones and tablets, both AMD and Intel are also affected by the Spectre bug.


There is no software fix for the Spectre bug, meaning that computers will be vulnerable for the foreseeable future. In comparison, Meltdown bug largely affects Intel chips and is easier to solve with a software update.

CPU Security Flaw Meltdown

Both bugs could allow malicious software, such as a computer virus, to steal passwords, emails, personal photos and other sensitive information from both your computer and mobile phone.

The US government warned that the only way to fully fix the problems was to replace the CPU, the main processor in a computer or phone. The underlying vulnerability is primarily caused by CPU architecture design. Fully removing the vulnerability requires replacing vulnerable CPU hardware.

Fix for Intel CPU flaws could slow down PCs and Macs
