Who should care

Security teams, endpoint administrators, vulnerability management owners, and anyone still responsible for legacy systems that may have Adobe Flash Player installed or enabled. Organizations with unsupported software inventories should treat this as a cleanup priority.

Technical summary

The source corpus identifies the issue as an integer underflow in Adobe Flash Player. CISA lists the vulnerability in KEV and notes that the impacted product is end-of-life and/or end-of-service, which means remediation is not a normal patch cycle. The available sources do not provide exploit details, affected versions, or a CVSS score.

Defensive priority

High. KEV inclusion means this vulnerability is prioritized for remediation, and the product is unsupported, so exposure should be eliminated as soon as possible.

Recommended defensive actions

  • Remove or disable Adobe Flash Player anywhere it still exists.
  • Inventory endpoints, virtual desktops, and legacy application environments for residual Flash Player components or dependencies.
  • Block or retire workflows that still rely on Flash content and migrate to supported alternatives.
  • Use the Adobe end-of-life guidance and alternative FAQ to plan replacement of any remaining business use.
  • Track the CISA KEV due date as an external remediation deadline and confirm exposure is closed before then.

Evidence notes

CISA’s KEV metadata names Adobe Flash Player and states the impacted product is end-of-life/end-of-service, with a required action to discontinue use. The official CVE and NVD records are linked in the source corpus, but the corpus does not supply a CVSS score, affected versions, or exploit narrative.
