CVE-2026-28527: CWE-125 Out-of-bounds Read in BlueKitchen GmbH BTstack
BlueKitchen BTstack versions prior to 1.8.1 contain an out-of-bounds read vulnerability in the AVRCP Controller GET_PLAYER_APPLICATION_SETTING_ATTRIBUTE_TEXT and GET_PLAYER_APPLICATION_SETTING_VALUE_TEXT handlers that allows nearby attackers to read beyond packet boundaries. Attackers can establish a paired Bluetooth Classic connection and send specially crafted VENDOR_DEPENDENT responses to trigger out-of-bounds reads, causing information disclosure and potential crashes on affected devices.
AI Analysis
Technical Summary
CVE-2026-28527 is an out-of-bounds read vulnerability (CWE-125) in BlueKitchen GmbH's BTstack Bluetooth stack versions prior to 1.8.1. The issue exists in the AVRCP Controller's handling of GET_PLAYER_APPLICATION_SETTING_ATTRIBUTE_TEXT and GET_PLAYER_APPLICATION_SETTING_VALUE_TEXT commands. An attacker with the ability to pair a Bluetooth Classic connection can send specially crafted VENDOR_DEPENDENT responses that cause the stack to read memory beyond intended packet boundaries. This can result in information disclosure and potentially cause device crashes. The vulnerability has a CVSS 4.0 base score of 2.1, reflecting low severity due to attack complexity and limited impact. No patch or official remediation details are currently available.
Potential Impact
The vulnerability allows an attacker with paired Bluetooth Classic access to cause out-of-bounds reads, potentially disclosing information from memory and causing device instability or crashes. The low CVSS score indicates that the impact is limited and exploitation requires user interaction and proximity. There are no known exploits reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit Bluetooth Classic pairing to trusted devices only and monitor for unusual Bluetooth activity. No official patch or workaround information is provided in the current data.
