Lifecycle Timeline
2Description
Meshtastic is an open source mesh networking solution. A fault in the handling of mesh packets containing invalid protobuf data can result in an attacker-controlled buffer overflow, allowing an attacker to hijack execution flow, potentially resulting in remote code execution. This attack does not require authentication or user interaction, as long as the target device rebroadcasts packets on the default channel. This vulnerability fixed in 2.6.2.
Analysis
Meshtastic is an open source mesh networking solution. Rated critical severity (CVSS 9.4), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
