How to fix?

Upgrade github.com/etcd-io/etcd/wal to version 3.4.10 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. It is possible to have an entry index greater then the number of entries in the ReadAll method in wal/wal.go. This could cause issues when WAL entries are being read during consensus as an arbitrary etcd consensus participant could go down from a runtime panic when reading the entry.
