CVE-2021-22364 — Huawei Mate 30 Firmware security vulnerability

Medium CVSS 5.5

There is a denial of service vulnerability in the versions 10.1.0.126(C00E125R5P3) of HUAWEI Mate 30 and 10.1.0.152(C00E136R7P2) of HUAWEI Mate 30 (5G) . A module does not verify certain parameters sufficiently and it leads to some exceptions. Successful exploit could cause a denial of service condition.

Matched remediation archetype

Resource exhaustion and denial of service

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

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
