CVE-2026-25634Public exploit

Memory corruption via profile-controlled overlapping memcpy

Published Feb 6, 2026 · Updated Feb 6, 2026

Memory corruption in International Color Consortium iccDEV before 2.3.1.4 allows local users to corrupt process memory via a crafted ICC profile. CIccXformMpe::Begin fails to reject mismatched transform channel counts, allowing CIccTagMultiProcessElement::Apply to pass overlapping SrcPixel and DestPixel stack ranges to memcpy. The attack requires user interaction to process the profile; the demonstrated result is an AddressSanitizer abort, while code execution depends on process context.
