Lifecycle Timeline
3DescriptionNVD
ESF-IDF is the Espressif Internet of Things (IOT) Development Framework. In versions 5.5.2, 5.4.3, 5.3.4, 5.2.6, and 5.1.6, a use-after-free vulnerability was reported in the BLE provisioning transport (protocomm_ble) layer. The issue can be triggered by a remote BLE client while the device is in provisioning mode. The vulnerability occurred when provisioning was stopped with keep_ble_on = true. In this configuration, internal protocomm_ble state and GATT metadata were freed while the BLE stack and GATT services remained active. Subsequent BLE read or write callbacks dereferenced freed memory, allowing a connected or newly connected client to trigger invalid memory acces. This issue has been patched in versions 5.5.3, 5.4.4, 5.3.5, 5.2.7, and 5.1.7.
AnalysisAI
Espressif IoT Development Framework versions 5.1.6-5.5.2 contain a use-after-free vulnerability in the BLE provisioning layer that allows remote attackers to trigger memory corruption when provisioning is stopped with keep_ble_on enabled. A connected BLE client can exploit freed GATT metadata through read/write callbacks to cause denial of service or potential code execution. …
