From 1.0.0-beta0001 until 4.1.2, ICC CLUT parsing calculates allocation sizes from attacker-declared channel and grid dimensions before confirming that the profile contains the declared values. IccDataReader.ReadClutF32 can request a large float array, and earlier public IccProfile.Entries parsing paths can allocate a large jagged representation, from a short truncated profile. In version 4, automatic image conversion reaches the parser when DecoderOptions.ColorProfileHandling is Convert; the default Preserve mode avoids that conversion path. The demonstrated impact is memory pressure and input-validation failure, not unhandled process termination. This issue is fixed in version 4.1.2.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":29.2,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":216718,"id":"CVE-2026-106114","ts":1791317869066,"field":"exploit_available","old":"false","new":"true"}]}
