CVE-2026-93015 PUBLISHED

BlueKitchen BTstack through 1.8.2 A2DP SEP Discovery Out-of-Bounds Write

Assigner: VulnCheck
Reserved: 17.09.2026 Published: 17.09.2026 Updated: 17.09.2026

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.
