CVE-2019-5210 — Huawei Nova 5I Pro Firmware security vulnerability

High CVSS 7.8

Nova 5i pro and Nova 5 smartphones with versions earlier than 9.1.1.190(C00E190R6P2)and Versions earlier than 9.1.1.175(C00E170R3P2) have an improper validation of array index vulnerability. The system does not properly validate the input value before use it as an array index when processing certain image information. The attacker tricks the user into installing a malicious application, successful exploit could cause malicious code execution.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
