Bitcoin Core Bugs Emerge as Fed Holds Rates and Traders Brace for $12B Expiry

Bitcoin Core bugs have emerged as BTC faces a fresh round of macroeconomic uncertainty. Developers disclosed three vulnerabilities on October 28, following AI-assisted security research by Project Loupe. The disclosures arrived just hours after the Federal Reserve held interest rates steady, leaving holders focused on Friday's $12 billion Bitcoin options expiry.

The vulnerabilities affect Bitcoin Core, the software used by nodes to verify transactions and enforce Bitcoin's rules. One flaw could allow malicious peers to crash nodes running Windows, macOS, and BSD. Another could gradually exhaust memory, while a third could corrupt blockchain undo data under extreme conditions.

Bitcoin Core developers have already released fixes across four maintained release branches. However, the timing puts network security alongside monetary policy and derivatives positioning in an unusually busy week.

Bitcoin Core Bugs and Node Security

The most serious of the three disclosed issues involves unbounded memory growth through TCP urgent data. A malicious peer could bypass normal memory protections and overwhelm vulnerable nodes running non-Linux operating systems. This flaw does not affect Linux nodes.
