CVE-2026-21316: Audition | Access of Memory Location After End of Buffer (CWE-788)

Audition versions 25.3 and earlier are affected by an Access of Memory Location After End of Buffer vulnerability that could lead to application denial-of-service. An attacker could exploit this vulnerability to cause the application to crash or become unresponsive. Exploitation of this issue requires user interaction in that a victim must open a malicious file.

Security readout for executives and security teams

Plain-English summary

A malicious file opened in Adobe Audition 25.3 or earlier can make the application crash or stop responding. The cited impact is disruption to availability, not theft or alteration of data. Because exploitation requires a user to open the file, exposure depends on both vulnerable installations and untrusted file handling.

Executive priority

Treat this as a normal-priority availability issue rather than an emergency compromise. Promptly update exposed creative workstations because crashes can interrupt production, while prioritizing environments that frequently receive files from customers, partners, or public sources.

Technical view

CVE-2026-21316 is a CWE-788 out-of-bounds memory access affecting Adobe Audition. It is rated CVSS 3.1 5.5: local attack vector, low complexity, no privileges, required user interaction, unchanged scope, and high availability impact without cited confidentiality or integrity impact.

Likely exposure

Likely exposure is limited to endpoints running Audition 25.3 or earlier, particularly where users open files from external, unknown, or untrusted sources. The supplied structured version data is ambiguous, so organizations should verify exact affected and corrected releases against Adobe’s advisory.

Exploitation context

A victim must open a malicious file in Audition. Successful exploitation can crash or hang the application. The source bundle does not report active exploitation, and the CVE is not identified as being in CISA’s Known Exploited Vulnerabilities catalog.

Researcher notes

The narrative identifies versions 25.3 and earlier, while the structured affected entry contains markers 0, 25.6, and 26.0 with a default status of unaffected. That discrepancy prevents a definitive range interpretation from the bundle alone. No code-execution, confidentiality, integrity, or active-exploitation claim is supported.

Mitigation direction

  • Consult Adobe APSB26-14 for the definitive affected and corrected versions.
  • Update vulnerable Audition installations according to Adobe’s published guidance.
  • Restrict or scrutinize Audition files received from untrusted sources.
  • Prioritize systems where users routinely process externally supplied media.

Validation and detection

  • Inventory Adobe Audition installations and record their exact versions.
  • Compare installed versions with the affected range in Adobe APSB26-14.
  • Confirm updated endpoints report the vendor-designated corrected version.
  • Review application crash telemetry for unusual Audition failures after file opening.
  • Verify users handling external media receive appropriate file-safety guidance.
