Overview

AI description

Automated description summarized from trusted sources.

CVE-2024-52911 is a use-after-free vulnerability affecting Bitcoin Core versions 0.14.0 through 29.0. This flaw allows a node to access memory that has already been freed when validating a specially crafted block. The vulnerability arises because necessary transaction data, pre-calculated and cached during validation, can be destroyed while still being accessed by a background validation thread. An attacker capable of mining a block with sufficient proof-of-work could exploit this to crash victim nodes.

Description
Bitcoin Core through 28.x has a security issue, the details of which are not disclosed. The earliest affected version is 0.14.
