Memory disclosure via out-of-bounds presentation read
Published Jan 28, 2026 · Updated Jan 28, 2026
Out-of-bounds reads in Apple Keynote before 15.1 and iOS, iPadOS, and macOS before 26 allow attackers to disclose memory via a crafted file. Quick Look and Keynote file processing read beyond a buffer boundary when bounds checks fail on malformed presentation data; Apple has not identified the exact routine. Exploitation requires a user or application to process the malicious Keynote file; the documented consequence is process-memory disclosure, not modification or service interruption.

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.
