CVE-2026-111272 LibRaw CVE debrief

Who should care

Developers and administrators of image processing and decoding applications using LibRaw, especially those handling Nikon NEF/TIFF images, should assess exposure and consider necessary updates or mitigations.

Why it matters

This vulnerability allows attackers to cause heap-based out-of-bounds reads in LibRaw through version 0.22.2, potentially leading to application crashes and information disclosure when decoding crafted Nikon NEF/TIFF images. Developers and administrators of image processing applications should assess exposure and consider updates or mitigations.

• Potential application crashes when decoding crafted Nikon NEF/TIFF images.
• Information disclosure through out-of-bounds reads.
• Denial of service through application instability.
• Possible exploitation requires verification from official sources.

Technical summary

The `parseNikonMakernote()` function in LibRaw through 0.22.2 is vulnerable to a heap-based out-of-bounds read. By supplying a crafted Nikon NEF/TIFF image with a 5-byte ShotInfo tag declaring version 243, attackers can cause applications to read past a short ShotInfo buffer, potentially leading to application crashes. This vulnerability allows attackers to cause heap-based out-of-bounds reads in LibRaw through version 0.22.2, potentially leading to application crashes and information disclosure when decoding crafted Nikon NEF/TIFF images.

Defensive priority

Medium priority for image processing and decoding applications using LibRaw, especially those handling Nikon NEF/TIFF images.

Recommended defensive actions

• Assess exposure of image processing and decoding applications using LibRaw, especially those handling Nikon NEF/TIFF images.
• Verify if applications are using LibRaw version 0.22.2 or earlier and consider updating to a patched version if available.
• Implement input validation and error handling for image decoding to mitigate potential crashes.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
