Detailsinfo

A vulnerability was found in Espressif (affected version unknown). It has been classified as critical. This affects an unknown functionality of the component Bluetooth Mesh SDK. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. CWE is classifying the issue as CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

ESP-IDF is the official development framework for Espressif SoCs. In Espressif’s Bluetooth Mesh SDK (`ESP-BLE-MESH`), a memory corruption vulnerability can be triggered during provisioning, because there is no check for the `SegN` field of the Transaction Start PDU. This can result in memory corruption related attacks and potentially attacker gaining control of the entire system. Patch commits are available on the 4.1, 4.2, 4.3 and 4.4 branches and users are recommended to upgrade. The upgrade is applicable for all applications and users of `ESP-BLE-MESH` component from `ESP-IDF`. As it is implemented in the Bluetooth Mesh stack, there is no workaround for the user to fix the application layer without upgrading the underlying firmware.

The weakness was shared 06/25/2022 as GHSA-7f7f-jj2q-28wm. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2022-24893 since 02/10/2022. Neither technical details nor an exploit are publicly available.
