Security readout for executives and security teams
Plain-English summary
CVE-2021-0567 is an Android 11 local privilege escalation issue. A permissions bypass in RemoteViews could allow font file injection, potentially letting code already on the device gain higher privileges. The sources do not show active exploitation or a CVSS score.
Executive priority
Address through routine but timely mobile patch governance. This is not sourced as actively exploited, but local privilege escalation can increase the impact of malicious or compromised apps on affected Android 11 devices.
Technical view
The issue is in RemoteViews.java, specifically isRestricted, where a permissions bypass could allow font file injection. The CVE describes local escalation of privilege with no additional execution privileges and no user interaction required. Affected product evidence is limited to Android 11.
Likely exposure
Exposure is most relevant to Android 11 devices, including devices covered by the Pixel June 2021 security bulletin. Confirm device OS version and patch level through MDM, EDR, or fleet inventory.
Exploitation context
The provided sources state local escalation of privilege and no user interaction. They do not provide exploit details, public exploitation evidence, or CISA KEV listing. Treat exploitation status as unconfirmed.
Researcher notes
Evidence is limited to the CVE description and Android/Pixel bulletin reference. No CWE, CVSS vector, patch commit, or exploit status is provided in the bundle, so validation should focus on version, patch level, and vendor bulletin mapping.
Mitigation direction
- Apply vendor-provided Android or Pixel security updates referenced by the June 2021 bulletin.
- Prioritize Android 11 devices with sensitive apps, shared use, or weak app installation controls.
- Check OEM guidance for non-Pixel Android 11 devices before assuming patch availability.
- Restrict untrusted app installation where enterprise controls allow it.
Validation and detection
- Inventory devices running Android 11 and record their security patch levels.
- Confirm whether devices received the applicable June 2021 Android or Pixel security update.
- Review MDM compliance policies for minimum Android security patch level enforcement.
- Check vendor advisories for device-specific backports or unsupported models.
