CVE-2026-93015 Details
Description
BlueKitchen BTstack through 1.8.2 fails to validate the peer-reported endpoint count against table bounds in A2DP stream endpoint discovery. A bonded peer can send an AVDTP DISCOVER response with more endpoints than the fixed table holds, causing out-of-bounds writes that corrupt adjacent static objects and crash the process or sever event delivery.
A vulnerability in BlueKitchen BTstack versions through 1.8.2 allows for out-of-bounds writes during A2DP stream endpoint discovery. The issue arises because the software fails to properly validate the number of endpoints reported by a peer against the limits of its internal table. As a result, a bonded peer can send an AVDTP DISCOVER response that includes more endpoints than the table can accommodate. This discrepancy leads to memory corruption by overwriting adjacent static objects, causing the process to crash or disrupting event delivery.
Users can update to BlueKitchen BTstack version 1.8.3 or later, where this vulnerability has been addressed.
