CVE-2022-26730Public exploitNetwork attack vector

Arbitrary code execution via malformed ICC profiles

Published Nov 1, 2022 · Updated May 6, 2025

Memory corruption in Apple macOS before 13 allows remote attackers to execute arbitrary code by inducing processing of a crafted image. ColorSync's CMMLutTag::InitializeCurveTable accepts user-controlled ICC curve parameters without validating their entry counts and sizes, corrupting memory. Successful exploitation requires the target to process the image and runs code with the privileges of the affected ColorSync-using application.
