CVE-2020-9107
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 confidenceAn out-of-bounds read and write vulnerability exists in Huawei P30 Pro devices due to insufficient validation of message parameters. An unauthenticated attacker can send a malformed message with specific parameters to trigger the vulnerability, causing an out-of-bounds memory access that leads to a process reboot (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 run 'getprop ro.product.model' via ADB shellAffected if Model number shows anything other than Huawei P30 Pro (device is not affected)
-
Check firmware versionNavigate to Settings > About Phone > Version, or run 'getprop ro.build.version.emui' via ADB shellAffected if Version number is less than 10.1.0.160(C00E160R2P8)
-
Identify the baseband/MSS versionNavigate to Settings > About Phone > Version > Build number, or run 'getprop ro.confidentiality.version' via ADB shellAffected if Baseband version corresponds to a build before C00E160R2P8 patch level
-
Check if message/radio services are exposedReview running services via 'dumpsys' or check for open network ports related to messaging (note: specific service name not provided in advisory)Affected if Untrusted network inputs can reach the message handling service
Device is affected if it is a Huawei P30 Pro running firmware version below 10.1.0.160(C00E160R2P8) and the vulnerable message handling service is exposed to untrusted inputs.

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
Update HUAWEI P30 Pro to version 10.1.0.160(C00E160R2P8) or later to patch the vulnerability. Until updated, limit exposure by avoiding untrusted network inputs to affected services.
