Description

Multiple vulnerabilities were identified in BlueZ, the Bluetooth protocol stack for Linux, including a flaw in parsing certain AVRCP profile responses that could lead to out-of-bounds memory access. These issues could cause crashes, denial of service, or potentially expose sensitive information. The vulnerabilities affect several Ubuntu LTS releases and have been addressed by updates provided by Ubuntu.

Technical Analysis

BlueZ contains multiple security issues, including an incorrect handling of AVRCP profile responses (CVE-2026-85218) that may allow an attacker to access out-of-bounds memory, potentially causing a crash or information disclosure. Other related vulnerabilities involve stack buffer overflows, denial of service via crafted XML input, and improper packet length validation. These vulnerabilities affect Ubuntu 16.04 LTS through 26.04 LTS versions of BlueZ. Ubuntu has released patches to address these issues in updated BlueZ package versions.

Potential Impact

Exploitation of these vulnerabilities could result in denial of service conditions or exposure of sensitive information due to out-of-bounds memory reads. Some flaws may also allow arbitrary code execution via stack buffer overflow. The impact is limited to affected BlueZ versions on Ubuntu LTS releases.

Mitigation Recommendations

A fix is available. Users should apply the security updates provided by Ubuntu as detailed in the Ubuntu Security Notice USN-8908-1. Updating BlueZ to the patched versions listed for each Ubuntu release will remediate these vulnerabilities. No additional mitigation steps are indicated by the vendor.
