Bitcoin Core Discloses Bug That Could Let Miners Crash Nodes or Run Code

Bitcoin Core disclosed CVE-2024-52911, a high-severity bug that could let miners crash nodes or execute code on versions 0.14.1 through 28.4. Bitcoin Core said the attack likely went unused because miners would need to mine invalid blocks and give up the coinbase reward. Cory Fields privately reported the bug in November 2024, and Bitcoin Core 29.0 shipped with the fix by April 2025. One popular estimate suggests as much as 43% of Bitcoin nodes still run vulnerable pre-v29 software.
