AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H
Adjacent vector confirmed by Bluetooth proximity requirement; UI:R reflects mandatory pairing interaction; A:H for daemon crash; C:L for potential heap leak with no integrity impact.

2DescriptionCVE.org
A flaw was found in BlueZ. Insufficient validation of packet length fields in GetFolderItems responses within the Audio/Video Remote Control Profile (AVRCP) implementation allows a malicious Bluetooth device within range to cause an out-of-bounds memory read. This vulnerability, affecting the parse_media_element() and parse_media_folder() functions, can lead to a crash of the bluetoothd daemon, resulting in a Denial of Service (DoS). It could also potentially expose sensitive heap memory contents. Exploitation requires user interaction to pair with the malicious device.
AnalysisAI
Out-of-bounds memory read in BlueZ's AVRCP implementation allows a physically proximate attacker - within Bluetooth radio range - to crash the bluetoothd daemon and potentially leak heap memory contents by sending a malformed GetFolderItems response. The flaw resides in parse_media_element() and parse_media_folder(), which fail to validate packet length fields before reading. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete prerequisites: (1) the attacker must be within Bluetooth radio range of the target system (typically 10-100 meters depending on Bluetooth class), and (2) the victim user must interactively pair with the attacker-controlled malicious Bluetooth device - this is explicit in the description and reflected in UI:R in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H (score 6.3) accurately reflects the moderate-to-high real-world risk profile: the adjacent-network vector constrains exploitation to physical Bluetooth proximity, and the required user interaction (device pairing) is a meaningful barrier that eliminates remote mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker brings a Bluetooth-capable device (e.g., a laptop running a custom BlueZ or a modified firmware device) within radio range of a vulnerable Linux host and presents it as an audio device. After socially engineering or waiting for the victim to initiate or accept a Bluetooth pairing, the attacker's device sends a crafted GetFolderItems AVRCP response with manipulated length fields, triggering the out-of-bounds read in parse_media_element() or parse_media_folder(), crashing bluetoothd and potentially exposing heap contents. … |
| Remediation | Apply the BlueZ package update for your RHEL version as released via Red Hat's security errata, referenced at https://access.redhat.com/security/cve/CVE-2026-75032. … Detailed patch versions, workarounds, and compensating controls in full report. |
