CVE-2020-0254
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.

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 confidenceAn out-of-bounds read vulnerability in Android SoC (System-on-Chip) firmware allows reading memory outside intended boundaries due to an incorrect bounds check. This could enable a remote attacker to access sensitive data from adjacent memory regions without authentication.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 the SoC vendor and modelCheck /proc/cpuinfo or run 'getprop ro.hardware' or 'cat /proc/device-tree/model' to identify the SoC vendor (Qualcomm, MediaTek, Samsung Exynos, etc.) and model numberAffected if The device uses an affected SoC firmware - this vulnerability exists in SoC firmware, not the Android OS layer directly
-
Determine the baseband firmware versionCheck the baseband version using 'getprop gsm.version.baseband' or 'getprop radio.version' - this shows the SoC firmware versionAffected if The baseband firmware version matches an unpatched version for the identified SoC vendor
-
Check the Android security patch levelRun 'getprop ro.build.version.security_patch' to see the installed security patch dateAffected if The security patch level is earlier than the month the CVE was patched in the Android Security Bulletin
-
Identify the SoC-specific firmware componentCheck the SoC vendor's security advisory for CVE-2020-0254 to identify the specific firmware component affected (baseband, modem, Wi-Fi, Bluetooth, etc.)Affected if The identified SoC component is present and its firmware version is unpatched
A device is affected if it runs an Android version with unpatched SoC firmware - specifically if the baseband/modem firmware version predates the vendor patch for this bounds check vulnerability and the device has not received the Android security update containing the SoC vendor fix.

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 security patches released through the Android Security Bulletin for the affected SoC components. Identify and update all affected devices in the fleet, as the fix requires a firmware update from the SoC vendor and device manufacturer.
