Bitcoin Core discloses three human-validated Project Loupe LLM-found bugs and patched releases

On 28 October 2026 Bitcoin Core issued three advisories for Project Loupe LLM-scan findings, covering TCP urgent-data memory exhaustion on non-Linux nodes, paused-peer memory growth and an undo-file overflow. Maintainers verified reports, fixed and backported changes into 29.5/30.4/31.2/32.1; the undo-file edge case still affects some 32-bit/FAT32 contexts. Individual findings date from July, September and October. This is an October 28 disclosure-and-patch milestone, not three new discoveries on that day, an observed attack or proof of autonomous remediation.
