CVE-2020-26598
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 8.0, 8.1, and 9.0 software. The Network Management component could allow an unauthorized actor to kill a TCP connection. The LG ID is LVE-SMP-200023 (October 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 confidenceA vulnerability in the Network Management component of LG mobile devices running Android 8.0, 8.1, and 9.0 allows an unauthorized actor to forcefully terminate (kill) TCP connections, enabling denial-of-service attacks against network communications.

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.
-
Identify device manufacturer and modelUse MDM inventory or run 'adb shell getprop ro.product.manufacturer' and 'adb shell getprop ro.product.model' to confirm the device is an LG mobile deviceAffected if Manufacturer is not LG - device is not affected by this specific vulnerability
-
Determine Android OS versionRun 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android version to identify the installed Android versionAffected if Version equals 8.0, 8.1, or 9.0 - device falls within the affected version range
-
Check security patch levelRun 'adb shell getprop ro.build.version.security_patch' to retrieve the installed security patch dateAffected if Patch level is earlier than the date when LG released the fix for this vulnerability (specific date varies by device model)
-
Verify Network Management component exposureReview if any network management services are exposed to unauthorized apps by checking app permissions or using 'adb shell dumpsys' to list active servicesAffected if Network Management component is accessible without authentication or proper permission controls
The device is affected if it is an LG mobile device running Android 8.0, 8.1, or 9.0 and the vendor security patch for this vulnerability has not been applied.

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 dataApply vendor-provided security patches from LG; if unavailable, consider upgrading to a supported Android version or replacing affected devices, and implement network-level controls to detect or block connection termination attempts.
