Overview
The cybersecurity world is yet again faced with another critical vulnerability, CVE-2025-22435, which, if exploited, could lead to severe system compromise or data leakage. This vulnerability resides in ‘avdt_msg_ind’ of ‘avdt_msg.cc’, causing a possible memory corruption due to type confusion. This vulnerability is especially dangerous as it does not require any additional execution privileges or user interaction for exploitation, making any paired device potentially susceptible to an escalated privilege attack.
This article will delve into the details of CVE-2025-22435, discussing the severity and potential impact of this vulnerability, the affected products, and how the exploit works. We will also provide guidance for mitigation to help you secure your systems against this flaw.

How the Exploit Works
The CVE-2025-22435 vulnerability is a memory corruption flaw caused by type confusion in the ‘avdt_msg_ind’ of ‘avdt_msg.cc’. This vulnerability could be exploited by an attacker sending a specifically crafted message to the targeted system. This message would lead to type confusion, leading to memory corruption.
An attacker exploiting this vulnerability could escalate their privileges on the paired device without any additional execution privileges needed, making this a highly severe vulnerability. Since it does not require user interaction, the exploit could be launched silently, making detection and prevention more challenging.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited:
# Attacker device
bluetoothctl
[bluetooth]# pair <target_device_mac_address>
[bluetooth]# trust <target_device_mac_address>
[bluetooth]# connect <target_device_mac_address>
[bluetooth]# send-message <crafted_message>This sequence of commands represents how an attacker might pair to a vulnerable device and send a crafted message that could exploit the vulnerability. Please note that this is a simplified representation and actual exploitation would likely involve more sophisticated techniques and commands.
