Summary

CVE-2026-24450 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Libraw Libraw. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-24450 is an integer overflow vulnerability (CWE-190) in the uncompressed_fp_dng_load_raw functionality of LibRaw at commit 8dc68e2. The flaw occurs when processing a specially crafted malicious DNG file, leading to a heap buffer overflow. LibRaw is a popular open-source library used for reading RAW image files, including Adobe's Digital Negative (DNG) format, and is integrated into various image processing applications and tools.

The vulnerability has a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is exploitable over the network with high attack complexity but no privileges or user interaction required. An attacker can supply a malicious DNG file to a vulnerable LibRaw instance—such as in applications that automatically process images from untrusted sources like email attachments, web uploads, or shared storage—potentially achieving remote code execution, data corruption, or denial of service through the resulting heap overflow.

Mitigation details are available in the Talos Intelligence advisory at https://talosintelligence.com/vulnerability_reports/TALOS-2026-2363. Security practitioners should update to a patched version of LibRaw beyond commit 8dc68e2 and validate image files before processing with the library.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

SI-10 Information Input Validation partial match

Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.

A.8.27 Secure system architecture and engineering principles partial match
degrades

Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.
