CVE intelligence and bounded remediation

CVE-2020-7122 — Two memory corruption vulnerabilities in the Aruba CX Switches Series 6200F, 6300, 6400, 8320, 8325, and 8400 have been found

High CVSS 7.5

Two memory corruption vulnerabilities in the Aruba CX Switches Series 6200F, 6300, 6400, 8320, 8325, and 8400 have been found. Successful exploitation of these vulnerabilities could result in Local Denial of Service of the CDP (Cisco Discovery Protocol) process in the switch. This applies to firmware versions prior to 10.04.1000.

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.
