CVE-2020-25063
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 · uneditedAn issue was discovered on LG mobile devices with Android OS 7.2, 8.0, 8.1, 9, and 10 software. An application crash can occur because of incorrect application-level input validation. The LG ID is LVE-SMP-200018 (July 2020).
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 confidenceLG mobile devices with Android OS 7.2 through 10 contain an input validation vulnerability at the application level that can be triggered to cause an application crash. The issue stems from improper validation of user input within LG's bundled applications, allowing potentially malicious or malformed input to cause a denial-of-service condition through application failure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device manufacturer is LGCheck the device settings: Settings > About Phone > Manufacturer or Brand. Alternatively, run 'getprop ro.product.manufacturer' or 'getprop ro.product.brand' via ADB shell.Affected if Device is not manufactured by LG, then this specific vulnerability does not apply
-
Check Android OS versionNavigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell.Affected if Version matches 7.2, 8.0, 8.1, 9.0, or 10.0 exactly - note these are specific point releases not ranges
-
Identify LG bundled applicationsReview the list of pre-installed applications on the device. Check Settings > Apps > All for applications branded as LG (such as LG Calendar, LG Notes, LG Email, or other LG system apps).Affected if LG bundled applications are installed on the device; the vulnerability exists in these custom LG applications, not in stock Android apps
-
Verify the input validation conditionThis is an application-level vulnerability triggered by malformed input to LG applications. There is no simple command to verify the flaw; exposure is determined by the combination of LG device + affected Android version + presence of unpatched LG applications.Affected if All three conditions are met: (1) LG device, (2) Android 7.2/8.0/8.1/9.0/10.0, (3) vulnerable LG bundled applications present and not patched
User is affected if they use an LG mobile device running Android 7.2, 8.0, 8.1, 9.0, or 10.0 with unpatched LG bundled applications installed; the vulnerability cannot be triggered on non-LG devices or other Android versions.

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.
From vendor dataLG should release patches for affected devices addressing the input validation flaw in their applications; users should apply available system and application updates from LG to remediate this vulnerability.
