A High-Severity Bug Could Have Stalled Bitcoin Mining—Bitcoin Core Has a Fix
Summary
Bitcoin Core disclosed three fixed vulnerabilities affecting denial-of-service and privacy protections. The highest-severity flaw could corrupt a node’s mempool after a chain reorganization, preventing miners from building block templates until restart. Another could stall block processing, while a Tor-related bug weakened protections for inbound connections. The flaws did not enable coin theft, unauthorized issuance or network-wide splits, and developers reported no evidence of exploitation. Operators are urged to update. The disclosures follow a policy change that accelerates handling of vulnerabilities easily found with AI.
