CVE-2021-39995 — Some Huawei products use the OpenHpi software for hardware management

Medium CVSS 6.8

Some Huawei products use the OpenHpi software for hardware management. A function that parses data returned by OpenHpi contains an out-of-bounds read vulnerability that could lead to a denial of service. Affected product versions include: eCNS280_TD V100R005C10; eSE620X vESS V100R001C10SPC200, V100R001C20SPC200, V200R001C00SPC300.

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.
