A use-after-free issue was addressed with improved memory management. This issue is fixed in watchOS 11.5, macOS Sonoma 14.7.6, tvOS 18.5, iPadOS 17.7.7, iOS 18.5 and iPadOS 18.5, macOS Sequoia 15.5, visionOS 2.5, macOS Ventura 13.7.6. Parsing a file may lead to an unexpected app termination.
Weakness
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
