CVE-2026-81980: Out-of-bounds Write (CWE-787) in Adobe Adobe Acrobat

CVE-2026-81980 is an out-of-bounds write vulnerability (CWE-787) in Adobe Acrobat Reader. Successful exploitation requires a victim to open a malicious file, which could allow arbitrary code execution within the context of the current user. The vulnerability affects Adobe Acrobat Reader versions up to 26.002.21900 and 24.001.30383. The CVSS v3.1 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.

Exploitation of 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 under the current user's context. However, exploitation requires user interaction (opening a malicious file). There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution when opening files from untrusted sources. Monitor Adobe's security advisories for updates and patches addressing this vulnerability.
