In Zephyr bluetooth mesh core stack, an out-of-bound write vulnerability can be triggered during provisioning.
AnalysisAI
In Zephyr bluetooth mesh core stack, an out-of-bound write vulnerability can be triggered during provisioning. Rated high severity (CVSS 8.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. In Zephyr bluetooth mesh core stack, an out-of-bound write vulnerability can be triggered during provisioning. Affected products include: Zephyrproject Zephyr.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
