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

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.
