Amazon Linux 2023 Security Advisory: ALAS2023-2026-2146
Advisory Released Date: 2026-09-14
Advisory Updated Date: 2026-09-14
Severity:
Important
Issue Overview:
A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution. (CVE-2026-80186)
Affected Packages:
