A use-after-free issue was addressed with improved memory management. This issue is fixed in macOS Sequoia 15.4, tvOS 18.4, macOS Ventura 13.7.5, iPadOS 17.7.6, macOS Sonoma 14.7.5, iOS 18.4 and iPadOS 18.4, visionOS 2.4. An attacker on the local network may be able to corrupt process memory.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
