AI Analysis

Impact

The vulnerability arises from a missing permission check in RingtoneFactory.getRingtone, allowing an application to access ringtone data without providing the required permissions. This results in local information disclosure; no privilege escalation or additional execution rights are required, and no user interaction is necessary for exploitation.

Affected Systems

The affected product is Google Android; any Android device that has not applied the latest security updates contains the vulnerable RingtoneFactory implementation.

Risk and Exploitability

An attacker who can execute code locally or run a malicious app on the device can directly query RingtoneFactory and read ringtone information. The exploit requires no elevated privileges and can be performed without prompting the user. Because EPSS data is unavailable and the vulnerability is not listed in the KEV catalog, the risk persists primarily on unpatched devices, but the likelihood of exploitation is considered non‑negligible due to the simplicity of the attack path.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Install the latest Android security patch that includes the RingtoneFactory permission check fix.
  • Restrict or revoke app permissions that grant unprivileged access to ringtone data, such as READ_EXTERNAL_STORAGE or the specific permission required to invoke RingtoneFactory.
  • If patching is delayed, enforce a device policy or sandbox to block unprivileged apps from calling RingtoneFactory or disable the exposed API through configuration.
