Memory disclosure via crafted DNG file
Published Feb 10, 2026 · Updated Feb 10, 2026
Out-of-bounds read in Adobe DNG SDK 1.7.1 build 2410 and earlier allows attackers to disclose process memory via a crafted file. Adobe identifies DNG-file processing as the affected surface but has not published the parser locus or unchecked field that causes the read beyond a buffer. Exploitation requires a victim to open a malicious file in software that incorporates the SDK; the reported consequence is memory disclosure only.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
