A use-after-free issue was addressed with improved memory management. This issue is fixed in iOS 17.1 and iPadOS 17.1, watchOS 10.1, iOS 16.7.2 and iPadOS 16.7.2, macOS Sonoma 14.1, Safari 17.1, tvOS 17.1. Processing web content may lead to arbitrary code execution.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
