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).
macOS Big Sur 11.5.1 is also bringing this security patch to Macs. Users are strongly recommended to update their devices to the latest macOS 11.5.1 and iOS 14.7.1 to patch these flaws.
iOS 14.7 had addressed a long list of security bugs
Last week, Apple released iOS 14.7 and iPadOS 14.7 to the public, patching a long list of security vulnerabilities. This update was delivered after a collaborative investigation revealed how the Israeli spyware, Pegasus, was routinely targeting iPhones - even the latest ones running the latest versions of iOS.

Security researchers, human rights activists, and journalists had called on Apple to do more to improve iOS security, especially since the outside security community has had a difficult time reaching out to or working with Apple to address potential security problems. It is likely that Apple will finally start listening to security researchers and will be more aggressive with patching up security vulnerabilities before they end up weaponizing spyware.
