Summary

OpenSynergy BlueSDK (aka Blue SDK) through 6.x has improper input validation within the BlueSDK Bluetooth stack. The issue results from the lack of proper validation of the remote L2CAP channel ID (CID), allowing an attacker to create an L2CAP channel with the null identifier assigned as a remote CID.

Risk Assessment

The vulnerability may be exploited by an attacker within Bluetooth range to disrupt or bypass Bluetooth stack mechanisms, potentially affecting device confidentiality and stability.

Recommendation
