Summary
libexif vulnerabilities
Details
It was discovered that libexif had an integer overflow in its MakerNote decoder when called with a zero-length buffer. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. (CVE-2026-32775)
It was discovered that libexif had an integer overflow in its Nikon MakerNote handler on 32-bit systems. A local attacker could possibly use this issue to cause a denial of service or obtain sensitive information. (CVE-2026-40385)
It was discovered that libexif had an integer underflow in its size checking for Fuji and Olympus MakerNote decoding. An attacker could possibly use this issue to cause a denial of service or obtain sensitive information. (CVE-2026-40386)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
