"The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that
are affected by multiple vulnerabilities as referenced in the USN-8908-1 advisory.

    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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
