Wu Shuo learns that the Bitcoin Core Project, the core development team of Bitcoin, has issued a high-severity security alert (CVE-2024-52911), stating that between Bitcoin Core versions 0.14.0 and 29.0, nodes may trigger a memory error when validating specially crafted blocks, leading to remote crashes. The announcement points out that the vulnerability stems from cached data being prematurely released during transaction validation and accessed by background threads. If an attacker can construct a block with sufficient computational power, it may cause the node to crash and potentially pose a remote code execution risk.
