Apple today released its second minor update to iOS 15 and iPadOS 15, which includes an “important security update” for a zero-day bug under active exploitation.

iOS 15.0.2 and iPadOS 15.0.2, which are available to download on supported devices now, include a fix for a memory corruption vulnerability that allowed an application to execute arbitrary code with the highest level of device access, Apple says on its security support page.
