CVE-2025-36911 is a high-severity vulnerability affecting Google Android, classified with a CVSS score of 7.1. This vulnerability allows for remote (proximal/adjacent) information disclosure of user conversations and location due to a logic error in key-based pairing. Importantly, no additional execution privileges are needed for exploitation, and user interaction is not required.
The presence of this vulnerability poses significant risks to organizations, especially considering the sensitivity of the data potentially exposed. Attackers may leverage this flaw to gain unauthorized access to confidential conversations and location data.
Currently, the vulnerability is known to have a confirmed exploit, which emphasizes the urgency for defenders. Organizations using affected versions of Android should prioritize patching to mitigate the associated risks.
Organizations should address this vulnerability in their priority patch cycle, as the potential for exploitation could lead to serious consequences.
Vulnerability Details
In key-based pairing, there is a possible ID due to a logic error in the code. This could lead to remote (proximal/adjacent) information disclosure of user's conversations and location with no additional execution privileges needed. User interaction is not needed for exploitation.
The vulnerability is classified as high severity with a CVSS 3.1 score of 7.1. It falls under the CWE classification, which indicates a critical flaw that organizations must address. The vulnerability affects all versions of Android prior to the vendor patch.
Technical Analysis
The root cause of CVE-2025-36911 is a logic error in the key-based pairing implementation. This error allows attackers to exploit the adjacent network access vector, which requires low attack complexity. Notably, this vulnerability requires no privileges and does not need user interaction for successful exploitation.
The attack vector being adjacent network means that the attacker must be in close proximity to the victim's device. The impact on confidentiality is high, as sensitive user data is at risk of exposure. The integrity impact is low, and there is no availability impact.
Risk & Impact Analysis
Risk to organizations includes significant potential exposure of sensitive user information such as conversations and location. The blast radius of this vulnerability is considerable, affecting millions of Bluetooth audio devices globally. Organizations must understand that the exploitation of this vulnerability can lead to unauthorized access to critical data.
Given the CVSS score of 7.1, organizations should assess the urgency based on their deployment of affected products. The high exploitability score indicates that this vulnerability should be treated with high priority in the patch management lifecycle.
