Security readout for executives and security teams
Plain-English summary
CVE-2017-13293 is an Android kernel flaw in NFC handling that could let a local attacker gain higher privileges on an affected device. The provided sources say exploitation needs no user interaction and no additional execution privileges. The record does not provide CVSS scoring or evidence of active exploitation.
Executive priority
Treat this as high priority for Android fleets with legacy or unsupported devices. Kernel privilege escalation can materially increase device compromise impact, but the provided evidence does not show active exploitation.
Technical view
The issue is a missing bounds check in nfc_hci_cmd_received() in core.c, allowing a possible out-of-bounds write. The stated impact is local kernel privilege escalation on Android. Available source details are sparse and do not describe affected kernel branches, patch commits, or exploit prerequisites beyond local access.
Likely exposure
Exposure is likely limited to Android devices running affected, unpatched Android kernel builds covered by the April 2018 Android security bulletin. Unsupported legacy devices are the main concern because they may never have received OEM security updates.
Exploitation context
Provided sources support local escalation of privilege with no user interaction and no additional execution privileges. The source bundle marks KEV as false, and no cited source establishes active exploitation.
Researcher notes
Key gaps are missing CVSS data, absent CWE mapping, no patch commit in the provided bundle, and no affected branch detail. Analysis should stay anchored to Android kernel exposure and vendor bulletin status.
Mitigation direction
- Apply the Android April 2018 security bulletin fixes or later OEM security updates.
- Prioritize unsupported or legacy Android devices for upgrade or retirement.
- Check device vendor guidance for model-specific patch availability.
- Restrict use of unpatched Android devices in sensitive environments.
Validation and detection
- Inventory Android devices and record their Android security patch level.
- Confirm devices received the April 2018 Android security bulletin fixes or later.
- Identify models no longer receiving OEM kernel security updates.
- Track remediation exceptions for devices that cannot be updated.
