CVE intelligence and bounded remediation

CVE-2020-9125 — There is an out-of-bound read vulnerability in huawei smartphone Mate 30 versions earlier than 10.1.0.156 (C00E155R7P2)

Medium CVSS 6.7

There is an out-of-bound read vulnerability in huawei smartphone Mate 30 versions earlier than 10.1.0.156 (C00E155R7P2). An attacker with specific permission can exploit this vulnerability by sending crafted packet with specific parameter to the target device. Due to insufficient validation of the parameter, successful exploit can cause the device to behave abnormally.

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.
