Apple on Monday released an update to iOS, the software that runs iPhones and iPads, that fixes a major problem that haunted the processors in those devices. The flaw, dubbed Spectre by the researchers who found it, made the silicon chips vulnerable to a hacking attack that could reveal secret information your devices normally keep locked down.

The update comes less than a week after news broke that chips made by Intel, ARM and AMD contained the flaw. Researchers also found that most Intel chips have a second variation of the vulnerability, called Meltdown. The revelation of the flaws has been followed by a flurry of announcements by chip-makers, computer manufacturers and cloud service providers reassuring customers that they are finding ways to prevent hackers from using them.
