CVE-2026-24450
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn integer overflow vulnerability exists in the uncompressed_fp_dng_load_raw functionality of LibRaw Commit 8dc68e2. A specially crafted malicious file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceLibRaw's uncompressed_fp_dng_load_raw function in commit 8dc68e2 contains an integer overflow vulnerability that allows a heap buffer overflow when processing specially crafted DNG (Digital Negative) raw image files. The integer overflow occurs during size calculation, causing allocated buffer to be undersized, leading to subsequent heap overflow when data is written.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check LibRaw library versionRun `pkg-config --modversion libraw` or check the library file version with `strings libraw.so | grep -E "^0\.22\.1$"` or examine the binary linked against LibRaw with `ldd <executable> | grep -i raw`Affected if The installed version is exactly 0.22.1
-
Identify applications using LibRaw for image processingSearch for binaries that link to libraw using `ldconfig -p | grep -i raw` or `find /usr -name "*.so*" -exec ldd {} \; 2>/dev/null | grep -i libraw`Affected if Any application links against the vulnerable LibRaw 0.22.1 library
-
Verify DNG file processing capability is in useCheck if the application configuration or logs show DNG or raw image processing, or examine file access patterns for .dng file handling with `strace -e openat <app> 2>&1 | grep -i dng`Affected if The application processes DNG format files using LibRaw
-
Confirm the uncompressed_fp_dng_load_raw function is reachableIf debugging symbols are available, verify the function exists in the binary with `nm -C libraw.so | grep uncompressed_fp_dng_load_raw` or check if raw DNG processing code paths are exercisedAffected if The vulnerable code path for uncompressed DNG files is executed during image processing
A user is affected if they run LibRaw version 0.22.1 and process uncompressed DNG image files through the vulnerable uncompressed_fp_dng_load_raw function.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate LibRaw to a version containing the fix for CVE-2026-24450, or apply the patch addressing the integer overflow in uncompressed_fp_dng_load_raw with proper bounds validation before buffer allocation.
