Who should care

Security teams that still have Adobe Flash Player present on endpoints, legacy systems, kiosks, or embedded environments; asset owners responsible for application retirement and network isolation; and incident response teams monitoring known-exploited vulnerabilities.

Technical summary

The official record identifies the issue as a stack-based buffer overflow in Adobe Flash Player. The CISA KEV entry confirms the vulnerability is known to be exploited and adds remediation guidance specific to an end-of-life product: disconnect it if it remains deployed. No version ranges, exploit mechanics, or mitigation details beyond that guidance are provided in the supplied sources.

Defensive priority

High. CISA has placed the vulnerability in KEV, and the impacted product is end-of-life, so remaining installations should be treated as urgent removal or isolation candidates.

Recommended defensive actions

  • Inventory all systems for any remaining Adobe Flash Player installations or dependencies.
  • Remove or disable Adobe Flash Player wherever it is still present.
  • If immediate removal is not possible, disconnect affected end-of-life systems from networks as CISA recommends.
  • Prioritize remediation before the KEV due date of 2022-06-13 for any still-exposed assets.
  • Validate that legacy content and business workflows no longer require Flash-based components.

Evidence notes

Supported by official CVE and CISA KEV records only. The source corpus identifies the vulnerability name, product, and KEV status, and CISA notes that the impacted product is end-of-life and should be disconnected if still in use. The supplied sources do not provide affected versions, exploit details, or CVSS values, so those are intentionally omitted.
