Security readout for executives and security teams
Plain-English summary
CVE-2017-13310 is an Android local privilege escalation issue. A malicious app on an affected device could start an activity with system privileges, bypassing intended permission controls. The source says no user interaction is needed, but the attacker needs local app-level access.
Executive priority
Prioritize this for legacy Android fleets. It is high impact if a malicious app runs on an affected device, but the available sources do not show internet-scale exploitation or KEV listing.
Technical view
The issue is in createFromParcel of ViewPager.java and is described as a read/write serialization problem causing a permissions bypass. CVSS 3.1 is 7.8: local attack vector, low complexity, low privileges required, no user interaction, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to affected Android versions listed by the CVE: 6.0, 6.0.1, 7, 8, 8.1, and nyc-mr development branches. Managed fleets with old or unsupported Android builds are the main concern.
Exploitation context
The source bundle does not cite active exploitation, and KEV status is false. The described attacker position is a locally installed app with low privileges, not a remote unauthenticated network attacker.
Researcher notes
Evidence is limited to the CVE data and Android bulletin reference. Do not assume additional affected products or exploit availability. Focus validation on OS version, vendor patch mapping, and whether local app installation paths exist.
Mitigation direction
- Review the Android May 2018 security bulletin and vendor guidance for applicable fixes.
- Update affected devices to vendor builds that include the relevant Android security fixes.
- Retire or isolate unsupported Android 6, 7, and 8 devices where updates are unavailable.
- Restrict installation of untrusted apps, especially on legacy managed devices.
- Use MDM policy to reduce sideloading and enforce device compliance.
Validation and detection
- Inventory Android devices running versions listed as affected by the CVE.
- Verify vendor security patch levels against the Android May 2018 bulletin.
- Confirm unmanaged or unsupported devices are excluded from sensitive workflows.
- Review MDM controls for sideloading, app trust, and compliance enforcement.
- Document any affected devices that cannot receive vendor fixes.

Incorrect Default Permissions
Incorrect Default Permissions represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
