Sensitive memory disclosure via undisclosed out-of-bounds read
Published Jun 9, 2026 · Updated Jun 9, 2026
Out-of-bounds read in Adobe Acrobat Reader 26.001.21651 and earlier allows attackers to disclose sensitive process memory via a malicious file. Adobe identifies the flaw only by weakness class and does not disclose the affected parser, function, malformed field, or exact read operation. Exploitation requires a victim to open the file; the reported consequence is memory disclosure without integrity or availability impact.
