Summary

A heap-use-after-free vulnerability in the SLEIGH library before version 12.1 (Ghidra) exists in SleighBuilder::generatePointerAdd due to iterator invalidation when PcodeCacher::allocateInstruction reallocates the issued vector.

Risk Assessment

Attackers can trigger memory corruption by decompiling malicious binaries via the public Sleigh::oneInstruction C++ API, potentially causing application crashes or arbitrary code execution in downstream SLEIGH library consumers.

Recommendation

Upgrade Ghidra to version 12.1 or later immediately. For applications using the SLEIGH library as a dependency, update to a patched version.
