CVE-2026-0015 is a vulnerability identified in the Android operating system, specifically within the AppOpsService.java component. The root cause is improper input validation at multiple code locations, which allows an attacker to trigger a persistent denial of service condition. This vulnerability does not require any special privileges (PR:N) or user interaction (UI:N), making it easier to exploit locally. The flaw affects Android versions 14, 15, 16, and 16-qpr2. The denial of service is persistent, meaning the impact continues beyond a transient disruption, potentially requiring a device restart or other recovery actions. The CVSS v3.1 base score is 6.2, reflecting a medium severity with an attack vector limited to local access (AV:L), low attack complexity (AC:L), and no impact on confidentiality or integrity, only availability (A:H). The vulnerability is categorized under CWE-20, indicating improper input validation as the underlying weakness. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly.

The primary impact of CVE-2026-0015 is a local denial of service on affected Android devices, which can disrupt normal device operations and potentially cause persistent unavailability of certain services or the entire device. Since no privileges or user interaction are required, any local application or user on the device can exploit this vulnerability, increasing the risk in multi-user or shared device environments. Although confidentiality and integrity are not affected, the availability impact can degrade user experience and operational continuity, especially for critical mobile applications or enterprise environments relying on Android devices. Persistent DoS conditions may require device reboot or factory reset, causing downtime and potential data loss if unsaved data is present. Organizations with large Android deployments, particularly those using affected versions, may face increased support costs and operational disruptions if exploited.

To mitigate CVE-2026-0015, organizations and users should monitor for official patches or security updates from Google and apply them promptly once available. Until patches are released, limiting local access to trusted users and applications can reduce exploitation risk. Employing mobile device management (MDM) solutions to enforce strict app installation policies and restrict untrusted local applications can help prevent exploitation. Regularly auditing installed apps and removing unnecessary or suspicious software reduces the attack surface. Additionally, educating users about the risks of installing untrusted apps and maintaining device physical security can further mitigate local exploitation. Developers should review and harden input validation in custom Android services and apps to avoid similar issues. Monitoring device logs for abnormal AppOpsService behavior may help detect exploitation attempts.
