Lifecycle Timeline
1DescriptionNVD
The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets.
AnalysisAI
The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion. Rated medium severity (CVSS 6.5), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified under CWE-617. The Bluetooth Low Energy (BLE) controller implementation in Espressif ESP-IDF 4.0 through 4.2 (for ESP32 devices) returns the wrong number of completed BLE packets and triggers a reachable assertion on the host stack when receiving a packet with an MIC failure. An attacker within radio range can silently trigger the assertion (which disables the target's BLE stack) by sending a crafted sequence of BLE packets. Affected products include: Espressif Esp-Idf. Version information: through 4.2.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Apply vendor patches when available. Implement network segmentation and monitoring as interim mitigations.
