Official Description

iccDEV provides a set of libraries and tools for working with ICC color management profiles. In versions up to and including 2.3.1.4, signed integer overflow in iccFromCube.cpp during multiplication triggers undefined behavior, potentially causing crashes or incorrect ICC profile generation when processing crafted/large cube inputs. Commit 43ae18dd69fc70190d3632a18a3af2f3da1e052a fixes the issue. No known workarounds are available.

Technical Analysis

CVE-2026-27691 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 5.5.

A proof-of-concept (PoC) exploit exists for CVE-2026-27691. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
