CVE-2025-36925 is a vulnerability identified in the Android kernel component, specifically within the WAVES_send_data_to_dsp function of the libaoc_waves.c source file. The root cause is a missing bounds check that leads to an out-of-bounds write (CWE-787). This type of memory corruption flaw allows an attacker with local access and limited privileges to write data beyond the intended buffer boundaries. Such an out-of-bounds write can corrupt adjacent memory structures, potentially allowing the attacker to escalate their privileges on the device. The vulnerability does not require any additional execution privileges or user interaction, making it easier to exploit once local access is obtained. The CVSS v3.1 base score is 7.8, reflecting high severity, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This vulnerability is significant because it affects the Android kernel, a critical component responsible for managing hardware and system resources. Exploiting this flaw could allow attackers to gain root-level access, bypass security controls, and potentially install persistent malware or extract sensitive data. No public patches or known exploits are currently available, but the vulnerability has been officially published and reserved since April 2025.

The impact of CVE-2025-36925 is substantial for organizations and individuals using affected Android devices. Successful exploitation can lead to full system compromise, allowing attackers to gain root privileges and bypass security mechanisms. This could result in unauthorized access to sensitive data, installation of persistent malware, disruption of device functionality, and potential lateral movement within enterprise environments. Since Android devices are widely used in both consumer and enterprise contexts, including mobile phones, tablets, and embedded systems, the vulnerability poses a risk to data confidentiality, system integrity, and availability. Enterprises relying on Android devices for secure communications or sensitive operations may face increased risk of espionage, data breaches, or sabotage. The lack of required user interaction and low complexity of exploitation further increase the threat level, especially in environments where physical or local access to devices is possible.

To mitigate CVE-2025-36925, organizations should prioritize applying official security patches from Google or device manufacturers as soon as they become available. Until patches are released, organizations should enforce strict access controls to limit local access to Android devices, including physical security measures and restricting debug or developer modes that could facilitate exploitation. Employing mobile device management (MDM) solutions to monitor and control device configurations can help detect suspicious activities. Additionally, disabling or restricting the use of vulnerable kernel modules or audio processing features related to libaoc_waves.c may reduce the attack surface, though this may impact device functionality. Regularly updating devices to the latest Android versions and security updates is critical. Security teams should also monitor for any emerging exploit code or indicators of compromise related to this vulnerability and be prepared to respond promptly. For high-security environments, consider isolating critical Android devices or using hardware-backed security features to limit privilege escalation risks.
