CVE-2018-7992 — Huawei Mediapad M3 Firmware security vulnerability

Medium CVSS 5.5

Mdapt Driver of Huawei MediaPad M3 BTV-W09C128B353CUSTC128D001; Mate 9 Pro versions earlier than 8.0.0.356(C00); P10 Plus versions earlier than 8.0.0.357(C00) has a buffer overflow vulnerability. The driver does not sufficiently validate the input, an attacker could trick the user to install a malicious application which would send crafted parameters to the driver. Successful exploit could cause a denial of service condition.

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.
