Who should care

Security teams, endpoint and asset owners, incident responders, and administrators responsible for legacy Adobe Flash Player deployments should prioritize this CVE, especially where outdated or isolated systems may still have Flash installed.

Technical summary

The supplied source corpus identifies the issue as a dereferenced pointer vulnerability in Adobe Flash Player. CISA classifies it as a known exploited vulnerability and notes the affected product is end-of-life. No further technical exploit details are provided in the supplied materials.

Defensive priority

High. This is a CISA KEV entry for an end-of-life product, so exposure should be treated as urgent until the affected software is removed or disconnected.

Recommended defensive actions

  • Inventory systems to confirm whether Adobe Flash Player is still present anywhere in the environment.
  • Remove Flash Player where possible; if removal is not immediately feasible, disconnect impacted systems as CISA recommends for end-of-life products still in use.
  • Restrict access to any legacy systems that cannot be retired immediately.
  • Verify compensating controls around remote access, browser use, and user execution paths on legacy hosts.
  • Track remediation against the CISA KEV due date associated with this entry (2022-06-15) for internal prioritization.
