Bitcoin Core 29.5, 30.4, 31.2 and 32.1 fix three AI-found bugs, including a remote crash of Windows, macOS and BSD nodes ยท updates https://pwn.watch/i/bitcoin-core-ai-found-node-crash-bugs-oct-2026 Bitcoin Core published three advisories on Oct 28 2026 for bugs first found by an automated LLM scan (Elias Rohrer's Project Loupe at Spiral) and validated by Gregory Sanders. The worst, rated Medium: on platforms other than Linux, a malicious peer can send TCP urgent (out-of-band) data to bypass read backpressure and queue unlimited data, which Bitcoin Core says lets it "trivially crash any Windows, macOS or BSD node it is connected to". A second Medium bug lets a peer that claims not to support BIP 31 pings stay paused forever while its message queue grows (up to 2MB per hour per inbound peer, 5MB per hour per outbound peer). A Low-severity undo-file overflow lets a miner corrupt other nodes' undo data, impractical on 64-bit systems. All three are fixed in 29.5, 30.4, 31.2 and 32.1 and were disclosed early under Core's new policy for "easily discoverable" bugs. en Wed, 28 Oct 2026 00:00:00 GMT Bitcoin Core 29.5, 30.4, 31.2 and 32.1 fix three AI-found bugs, including a remote crash of Windows, macOS and BSD nodes: Bitcoin Core discloses the three bugs (TCP urgent-data OOM, paused pre-BIP31 peer memory growth, undo-file overflow) with fixes in 29.5, 30.4, 31.2 and 32.1. Release notes say three more medium and high severity bugs fixed in 30.0 will be disclosed in two weeks. https://pwn.watch/i/bitcoin-core-ai-found-node-crash-bugs-oct-2026 https://pwn.watch/i/bitcoin-core-ai-found-node-crash-bugs-oct-2026#2026-10-28-75e31d66 Wed, 28 Oct 2026 00:00:00 GMT medium <p><a href="https://bitcoincore.org/en/security-advisories/">Source</a></p> Bitcoin Core 29.5, 30.4, 31.2 and 32.1 fix three AI-found bugs, including a remote crash of Windows, macOS and BSD nodes: Project Loupe's LLM scan flags the TCP urgent-data memory bug; Gregory Sanders validates it and notifies the Bitcoin Core security team the same day. https://pwn.watch/i/bitcoin-core-ai-found-node-crash-bugs-oct-2026 https://pwn.watch/i/bitcoin-core-ai-found-node-crash-bugs-oct-2026#2026-10-23-89109d7f Fri, 23 Oct 2026 00:00:00 GMT medium <p><a href="https://bitcoincore.org/en/2026/10/28/disclose-tcp-oom/">Source</a></p>
