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 · unedited
Certain detection module of P30, P30 Pro, Honor V20 smartphone whith Versions earlier than ELLE-AL00B 9.1.0.193(C00E190R1P21), Versions earlier than VOGUE-AL00A 9.1.0.193(C00E190R1P12), Versions earlier than Princeton-AL10B 9.1.0.233(C00E233R4P3) have a race condition vulnerability. The system does not lock certain function properly, when the function is called by multiple processes could cause out of bound write. An attacker tricks the user into installing a malicious application, successful exploit could cause malicious code execution.

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 · high confidence

Race condition in Huawei smartphone detection module. The system fails to properly lock a function, allowing multiple processes to simultaneously call it, causing an out-of-bounds write vulnerability. Exploitation requires user to install a malicious application, enabling arbitrary code execution.

MitigationUpdate affected devices (P30, P30 Pro, Honor V20) to the specified versions or later. Avoid installing applications from untrusted sources.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify your device model
    Check the device settings - typically found under Settings > About Phone > Model number
    Affected if Device is not a Huawei P30, P30 Pro, or Honor V20 (not affected)
  2. Check Huawei P30 firmware version
    Go to Settings > About Phone > Version. Compare the build number to elle-al00b_9.1.0.193(c00e190r1p21)
    Affected if Firmware version is lower than elle-al00b_9.1.0.193(c00e190r1p21)
  3. Check Huawei P30 Pro firmware version
    Go to Settings > About Phone > Version. Compare the build number to vogue-al00a_9.1.0.193(c00e190r1p12)
    Affected if Firmware version is lower than vogue-al00a_9.1.0.193(c00e190r1p12)
  4. Check Honor V20 firmware version
    Go to Settings > About Phone > Version. Compare the build number to princeton-al10b_9.1.0.233(c00e233r4p3)
    Affected if Firmware version is lower than princeton-al10b_9.1.0.233(c00e233r4p3)
  5. Review installed applications
    Go to Settings > Apps > App manager. Look for any applications installed from untrusted or unknown sources
    Affected if Malicious applications are present on the device (required for exploitation)

Device is affected if it is a Huawei P30, P30 Pro, or Honor V20 running firmware below the specified version AND has a malicious application installed.
