**Name of the Vulnerable Software and Affected Versions** Bytom versions prior to 1.0.6 **Description** The issue arises from improper validation of arguments in a query, which can lead to an out-of-bounds panic. This can be exploited as a vector for denial of service attacks, especially when processing queries from untrusted parties. The `checkTopicRegister` function in `p2p/discover/net.go` does not prevent negative `idx` values, resulting in a crash. **Recommendations** For Bytom versions prior to 1.0.6, update to version 1.0.6 or later to resolve the issue. As a temporary workaround, consider restricting the input validation to prevent negative `idx` values in the `checkTopicRegister` function until a patch is available.
