CWE-125 Out-of-bounds Read

Description

node-re2 provides RE2 regular expression bindings for Node.js. Prior to version 1.26.1, passing a Buffer whose final bytes form a truncated (incomplete) multi-byte UTF-8 sequence could cause the native binding to read past the end of the allocated buffer while attempting to decode the final, incomplete code point. This could result in an out-of-bounds read and potential disclosure of adjacent memory contents. This issue is fixed in version 1.26.1.
