A use-after-free issue was addressed with improved memory management. This issue is fixed in visionOS 2.2, tvOS 18.2, watchOS 11.2, iOS 18.2 and iPadOS 18.2, macOS Sequoia 15.2. Processing a maliciously crafted image 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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
