Apple has today released iOS 14.7.1 and iPadOS 14.7.1 to the public after last week's iOS 14.7 release. Today's update patches a security vulnerability that, Apple says, "may have been" exploited in the wild.

"An application may be able to execute arbitrary code with kernel privileges," the iPhone maker explains. "Apple is aware of a report that this issue may have been actively exploited." The company added that the memory corruption issue (tracked as CVE-2021-30807) has been resolved by improving memory handling. The security bug impacts iPhone 6s and later, iPad Pro (all models), iPad Air 2 and later, iPad 5th generation and later, iPad mini 4 and later, and iPod touch (7th generation).
