CVE-2021-26277
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe framework service handles pendingIntent incorrectly, allowing a malicious application with certain privileges to perform privileged actions.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThe vulnerability exists in a framework service that incorrectly handles PendingIntent objects. A malicious application possessing certain permissions can exploit this improper handling to execute privileged actions beyond what its actual permissions should allow, effectively achieving privilege escalation.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.
Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

-
Identify if Vivo Frame Service is installedCheck device applications for the Vivo Frame Service package. On Android, this can be done via 'pm list packages' or through Settings > Apps > Show system apps, looking for the Vivo framework service component.Affected if The Vivo Frame Service package exists on the device
-
Determine the installed version of Vivo Frame ServiceRetrieve the version of the Vivo Frame Service package. Use 'dumpsys package <package_name>' or check the app info in Settings to view the versionName/versionCode.Affected if The detected version is lower than 2021.6.30 (e.g., 2021.5.x, 2021.4.x, etc.)
-
Check if the device receives vendor updatesVerify whether the device manufacturer provides ongoing security updates for the framework service component. Check system update settings and the vendor support lifecycle documentation.Affected if The device is no longer receiving security updates from Vivo for the framework service
A user is affected if the Vivo Frame Service is present on their device and its installed version is older than 2021.6.30, indicating an unpatched vulnerable version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2021.6.30
Apply vendor-provided security patches for the framework service; review and restrict application permissions to minimum necessary; monitor for applications requesting unusual permission combinations.
2021.6.30
- Identify the current Frame Service version installed in the system
- Upgrade Frame Service to version 2021.6.30 or later to address the pendingIntent handling vulnerability
