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 device model
    Check your phone settings under Settings > About Phone to confirm the exact model number is one of: HONOR 20 PRO, Honor View 20, or HONOR 20
    Affected if Device model is not one of these three models
  2. Check firmware version
    Navigate to Settings > About Phone > Version to view the installed build number (format like 10.0.0.194(c432e9r5p1))
    Affected if Unable to determine firmware version from settings
  3. Compare Honor 20 Pro version
    If device is Honor 20 Pro, compare your build number against: 10.0.0.194(c432e9r5p1), 10.0.0.194(c636e3r3p1), 10.0.0.194(c00e62r8p12), or 10.0.0.194(c10e3r3p2)
    Affected if Installed version is lower than any of these four version strings
  4. Compare Honor View 20 version
    If device is Honor View 20, compare your build number against: 10.0.0.200(c185e3r3p3), 10.0.0.201(c636e3r4p3), 10.0.0.195(c00e62r4p11), or 10.0.0.201(c10e5r4p3)
    Affected if Installed version is lower than any of these four version strings
  5. Compare HONOR 20 version
    If device is HONOR 20, compare your build number against: 10.0.0.186(c185e2r2p1) or 10.0.0.194(c432e9r5p1)
    Affected if Installed version is lower than either of these two version strings

Device is affected if it is an Honor 20 Pro, View 20, or HONOR 20 running a firmware version lower than the specific build numbers listed for that model, as the vulnerability exists in those earlier versions due to improper exception handling.
