Executive Summary

This vulnerability is a potential Out-Of-Bounds (OOB) Write in the gen_prov_start function within the pb_adv.c file. It occurs because the full length of received data is copied into the link.rx.buf receiver buffer without checking if the data size fits, which can lead to writing outside the allocated buffer boundaries.

Impact Analysis

The vulnerability can lead to memory corruption due to out-of-bounds writes, which may cause application crashes, data corruption, or potentially allow an attacker to execute arbitrary code. According to the CVSS score, it has a high impact on availability and low impact on confidentiality and integrity.
