CVE-2026-79909 is a Use After Free vulnerability (CWE-416) in Adobe Acrobat that can lead to arbitrary code execution in the context of the current user. Successful exploitation requires the victim to open a malicious file, triggering the vulnerability. The CVSS 3.1 base score is 7.8, indicating high severity with attack vector local, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. No patch or official remediation information is currently available, and there are no known exploits in the wild at this time.

If exploited, this vulnerability could allow an attacker to execute arbitrary code with the privileges of the current user, potentially leading to full compromise of the affected system's user context. The requirement for user interaction limits the attack vector to scenarios where a user opens a malicious file.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening files from untrusted sources and follow best practices for handling potentially malicious documents.
