Ghidra < 12.1 - Heap-Use-After-Free in SleighBuilder::generatePointerAdd via Vector Reallocation

Ghidra before 12.1 contains a heap-use-after-free vulnerability in SleighBuilder::generatePointerAdd caused by iterator invalidation when PcodeCacher::allocateInstruction reallocates the issued vector. Attackers can trigger memory corruption by decompiling malicious binaries through the public Sleigh::oneInstruction C++ API, affecting downstream SLEIGH library consumers.

CWE-416 Use After Free

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
