A use after free issue was addressed with improved memory management. This issue is fixed in Safari 16.1, iOS 16.1 and iPadOS 16, macOS Ventura 13. Processing maliciously crafted web content may lead to arbitrary code execution.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
