Memory disclosure via use-after-free
Published Jun 9, 2026 · Updated Jun 9, 2026
Use-after-free in Adobe Acrobat Reader 26.001.21651 and earlier allows attackers to disclose process memory via a malicious file. Adobe has not disclosed the affected code path, object type, or operation that accesses memory after the object's lifetime ends. Exploitation requires a victim to open the file, and the documented standalone impact is memory disclosure without code execution.
