CVE-2026-0093: Android Local Privilege Escalation via Misleading UI—CVSS 7.8

Technical summary

The vulnerability exists due to obfuscation of UI elements in multiple locations within Android. The flaw manifests as a UI-based deception mechanism (CWE-451: User Interface (UI) Misrepresentation of Critical Information) that can be abused by local threat actors to escalate privileges. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates the attack surface is local, requires low attack complexity, a low-privilege user context, zero user interaction, and delivers confidentiality, integrity, and availability impact on the affected system. The absence of scope change means the impact is confined to the vulnerable component.

Business impact

Organizations deploying Android devices face a material risk of privilege escalation compromise. An insider or local attacker could leverage this vulnerability to access sensitive corporate data, modify system settings, or disable security controls on enrolled Android devices. For BYOD environments and enterprise MDM deployments, this increases the attack surface for credential theft, lateral movement, and data exfiltration. The lack of user interaction requirement during exploitation means even brief physical access or a compromised low-privilege app could trigger the flaw.

Affected systems

Google Android is affected across multiple versions and configurations. The vulnerability is present in multiple UI locations, suggesting it affects core Android functionality rather than a single component. Organizations should verify their specific Android versions against Google's advisory to determine which devices in their fleet require patching.

Exploitability

The vulnerability carries moderate-to-high exploitability risk. While exploitation requires local access and a low-privilege context (no system-level permissions needed), the complete absence of user interaction during the attack reduces friction significantly. An attacker does not need to socially engineer a user to click or approve anything—the misleading UI alone provides the escalation pathway. This makes the flaw dangerous in scenarios involving brief device access or malicious low-privilege applications.

Remediation

Remediation requires applying security patches from Google. The specifics of available patch versions should be obtained directly from Google's Android security advisory. Organizations should prioritize patching based on device criticality and user access patterns, particularly for devices handling sensitive data or used in high-risk roles.

Patch guidance

Consult Google's official Android security bulletin for the specific patch version addressing CVE-2026-0093. Verify the patch is compatible with your managed Android fleet and deploy via your mobile device management (MDM) solution to ensure broad coverage. Prioritize patching on BYOD and corporate-owned devices with access to sensitive systems or data. Testing should confirm that patching does not break existing business applications or MDM policies.

Detection guidance

Monitor for suspicious privilege escalation activity on Android devices using endpoint detection and response (EDR) tools compatible with Android. Log and alert on unexpected privilege elevation requests, unusual app permission grants, or access to sensitive system files by low-privilege processes. Review MDM logs for unauthorized system permission changes or unapproved app installations. Behavioral analysis can identify apps exploiting the misleading UI pattern to escalate privileges without user approval.

Why prioritize this

This vulnerability warrants HIGH priority due to its 7.8 CVSS score, local attack vector requiring only low privileges, zero user interaction requirement, and full impact on confidentiality, integrity, and availability. The UI obfuscation attack pattern is difficult for end-users to detect or prevent, making it an attractive target for both insider threats and malicious apps. The widespread nature (multiple locations in Android) increases the likelihood of exploitation.

Risk score, explained

The CVSS 7.8 HIGH severity reflects the combination of local-only attack surface, low complexity, low-privilege requirement, no user interaction, and complete compromise of system confidentiality, integrity, and availability. While the attack is local and does not cross system boundaries, the ease of execution and severity of impact justify elevated priority in patch and detection strategies.
