CVE-2026-47924 is a use-after-free vulnerability in Adobe Acrobat Reader affecting versions 24.001.30365, 26.001.21651, and earlier. The flaw exists in the handling of Annotation objects, where the application fails to properly validate that an object still exists before performing operations on it. This can result in dereferencing freed memory and exposing sensitive process memory contents. The issue is primarily an information disclosure vulnerability rather than a direct code execution flaw, although memory corruption of this type may be useful in exploit chains.
