AI Analysis

Impact

The vulnerability resides in multiple functions of Android's RemoteViews class, where a logic error allows applications to start activities in the background without proper authorization. This flaw permits a local attacker to elevate privileges on the device, gaining higher system capabilities without the need for additional execution privileges or user interaction. The weakness is a control‑flow bypass that violates intended access restrictions, enabling an app to execute privileged actions indirectly.

Affected Systems

Google Android operating systems are affected, specifically all device variants that include the vulnerable RemoteViews code. No specific version is listed in the September 2026 security bulletin, indicating that all Android releases present on or before that date may contain the flaw.

Risk and Exploitability

The CVE is designated as a local privilege escalation with no user interaction required. The EPSS score is < 1% and the vulnerability is not catalog. The CVSS score is 7.8, indicating a high severity. Because the flaw is present in system code, but the low EPSS score suggests that exploitation prevalence is execute the bypass without external triggers.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the Android September 1 2026 security patch that addresses the RemoteViews background activity launch bypass.
  • Ensure all device systems run the patched Android version, especially those accessed by local users on RemoteViews to launch background activities, disabling unnecessary privileges at the app level or via manifest settings.
  • Configure device policies to restrict background activity launches, or remove applications that use RemoteViews for background activities until the patch is applied.
