Summary
bluez vulnerabilities
Details
Michael Bommarito discovered that BlueZ incorrectly handled codec capability storage in the A2DP profile. An attacker could possibly use this issue to cause a stack buffer overflow, resulting in a denial of service or arbitrary code execution. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-19774)
It was discovered that BlueZ incorrectly handled packet length validation. An attacker could possibly use this issue to read out of bounds memory, causing a crash or exposing sensitive information. (CVE-2026-75032)
It was discovered that BlueZ incorrectly handled crafted XML input. An attacker could possibly use this issue to crash BlueZ, resulting in a denial of service. (CVE-2026-80185)
It was discovered that BlueZ incorrectly parsed remote names from Extended Inquiry Response data. An attacker could possibly use this issue to cause a stack buffer overflow, resulting in a denial of service or arbitrary code execution. (CVE-2026-80186)
Alexandro Calo discovered that BlueZ incorrectly parsed certain responses in the AVRCP profile. An attacker could possibly use this issue to access out of bounds memory, causing a crash or exposing sensitive information. (CVE-2026-85218)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
