The AI has come for my code

I was wondering if I would get a PR from some LLM on one of my repositories and lo! It has come to pass. I just received a notification that I have a PR for my 6809 assembler: Description: Four memcpy calls in opcodes.c copy opd->sz bytes from attacker-controlled source buffers (textstring.buf or buffer) into the fixed-size destination opd→bytes. The copy length opd->sz is derived from attacker-controlled assembly source input and is used directly without verifying it against the actual allocated size of opd→bytes or the actual length of the source buffer. When opd->sz exceeds the destination allocation, the memcpy writes beyond the end of opd→bytes, corrupting adjacent heap memory. On glibc systems this can be leveraged via tcache poisoning or other heap exploitation techniques to achieve arbitrary code execution. … Automated security fix by OrbisAI Security fix: add bounds check before memcpy in opcodes.c Okay. Let's see what you got. The table summary above the description lists…
