CVE-2021-22341 — There is a memory leak vulnerability in Huawei products

Medium CVSS 4.9

There is a memory leak vulnerability in Huawei products. A resource management weakness exists in a module. Attackers with high privilege can exploit this vulnerability by performing some operations. This can lead to memory leak. Affected product versions include:IPS Module V500R005C00SPC100,V500R005C00SPC200;NGFW Module V500R005C00SPC100,V500R005C00SPC200;NIP6300 V500R005C00SPC100,V500R005C10SPC200;NIP6600 V500R005C00SPC100,V500R005C00SPC200;Secospace USG6300 V500R005C00SPC100,V500R005C00SPC200;Secospace USG6500 V500R005C00SPC100,V500R005C10SPC200;Secospace USG6600 V500R005C00SPC100,V500R005C00SPC200.

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.
