Bitcoin Core discloses a high-risk vulnerability CVE-2024-52911, fixed in version 29.0
Deep Tide TechFlow News, May 6th, according to the official security announcement from Bitcoin Core, versions of Bitcoin Core 0.14.0 up to below 29.0 contain a high-risk vulnerability (CVE-2024-52911). Attackers can craft specially invalid blocks carrying valid proof of work to trigger nodes to access freed memory, causing remote crashes of the nodes, with a theoretical risk of remote code execution, but the likelihood is low.
This vulnerability was discovered and responsibly disclosed by MIT DCI researcher Cory Fields in November 2024. The fix patch was merged in December 2024, and the complete fix is included in Bitcoin Core version 29.0 (released in April 2025). The official recommends users upgrade to version 29.0 or higher as soon as possible.
