Who should care

Security teams, endpoint administrators, and asset owners who may still have Adobe Flash Player present on legacy systems should prioritize this CVE, especially because it is listed in CISA’s Known Exploited Vulnerabilities catalog.

Technical summary

The supplied corpus identifies the issue as a memory corruption vulnerability affecting Adobe Flash Player. No further technical details are provided in the source material, but CISA’s KEV listing indicates it is known to be exploited and that the impacted product is end-of-life.

Defensive priority

High. CISA’s KEV inclusion means this is a known-exploited issue, and the product is end-of-life, so the practical response is removal or disconnection rather than routine patching.

Recommended defensive actions

  • Inventory any remaining Adobe Flash Player installations across endpoints, VDI images, and legacy application hosts.
  • Remove or disable Adobe Flash Player wherever possible.
  • If the product must remain temporarily, disconnect the impacted system from networks as directed by the CISA KEV guidance in the supplied source.
  • Prioritize replacement or retirement of any business process still depending on Flash Player.
  • Validate that no browser plugins, runtimes, or embedded components remain enabled in managed environments.
