CVE-2026-75032— Bluez: bluez: out-of-bounds read in avrcp parse_media_element and parse_media_folder

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

BlueZ是BlueZ组织开源的一个蓝牙协议栈软件。 BlueZ存在缓冲区错误漏洞，该漏洞源于AVRCP实现中GetFolderItems响应的数据包长度字段验证不足，影响parse_media_element()和parse_media_folder()函数，可能导致越界内存读取，进而导致bluetoothd守护进程崩溃，造成拒绝服务，并可能泄露敏感堆内存内容。

Vulnerability Title
Bluez: bluez: out-of-bounds read in avrcp parse_media_element and parse_media_folder
Source: CVE Program / CVE List V5
Vulnerability Description
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.
