CVE-2020-9108
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 · uneditedHUAWEI P30 Pro versions earlier than 10.1.0.160(C00E160R2P8) have an out-of-bounds read and write vulnerability. An unauthenticated attacker crafts malformed message with specific parameter and sends the message to the affected products. Due to insufficient validation of message, which may be exploited to cause the process reboot.
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 the message handling component of HUAWEI P30 Pro smartphones. An unauthenticated attacker can send a malformed message with specific parameters to trigger an out-of-bounds read/write condition due to insufficient input validation. This memory corruption leads to a process reboot, causing denial of service.

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 model is Huawei P30 ProNavigate to Settings > About Phone > Model Number, or check the device physical label, to verify the exact modelAffected if The device is not a Huawei P30 Pro (other models are not affected by this specific CVE)
-
Check installed firmware versionNavigate to Settings > About Phone > Version, or access the device through mobile device management (MDM) if centrally managed, to view the current firmware build numberAffected if The firmware version is lower than 10.1.0.160(C00E160R2P8) - versions below this threshold contain the vulnerability
-
Verify messaging component is activeCheck that SMS/MMS messaging functionality is enabled on the device (Settings > Messages, or default messaging app is present and functional)Affected if The messaging component is disabled - if no messaging capability exists, the attack surface does not apply though the device remains technically vulnerable in firmware
The device is affected if it is a Huawei P30 Pro running firmware version lower than 10.1.0.160(C00E160R2P8) and has messaging functionality enabled.

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 data10.1.0.160
Upgrade HUAWEI P30 Pro to version 10.1.0.160(C00E160R2P8) or later to obtain the patched firmware. Organizations should inventory affected devices and push firmware updates through their mobile device management infrastructure.
