Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Safety: Premature garbage collection of Java-side wrapper objects can lead to the reclamation of underlying native memory buffers while references to them are still active, resulting in a classic use-after-free condition. Developers must ensure that native memory references explicitly pin or reference the Java-side owner object to prevent premature cleanup.
Memory Safety: Using standard malloc for structure allocations in the Objective-C runtime can leave fields, including critical pointers, uninitialized. This leads to undefined behavior or arbitrary pointer dereferencing when structures are traversed. Using calloc or explicit zero-initialization is mandatory.
