Bitcoin Core discloses bug that lets malicious peers crash Windows and macOS nodes
- —Flaw affects non-Linux nodes; Linux is not exposed
- —Root cause is a difference between select() and poll() socket monitoring
- —Patched in 29.5, 30.4, 31.2 and 32.1; no CVEs assigned
- —Bugs surfaced via Project Loupe, a scanner built at Spiral
Why it matters: A crashed node does not threaten funds, but it halts validation and transaction relay for operators who fail to update.
