CVE-2017-8202 — Huawei Prague-Al00A Firmware security vulnerability

High CVSS 7.1

The CameraISP driver of some Huawei smart phones with software of versions earlier than Prague-AL00AC00B205,versions earlier than Prague-AL00BC00B205,versions earlier than Prague-AL00CC00B205,versions earlier than Prague-TL00AC01B205,versions earlier than Prague-TL10AC01B205 has a buffer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP, the APP can send a specific parameter to the CameraISP driver of the smart phone, causing system reboot.

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.
