Arbitrary code execution via out-of-bounds write
Published Feb 10, 2026 · Updated Feb 10, 2026
Out-of-bounds write in Adobe DNG SDK 1.7.1 build 2410 and earlier allows attackers to execute arbitrary code through a malicious file. Adobe has not published the affected parser, function, or memory operation that writes beyond its intended buffer while processing the file. A local user must open the crafted file in an application built with the SDK, after which code runs in that user's context.

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.
