CVE-2025-71231 (GCVE-0-2025-71231)

Vulnerability from cvelistv5 – Published: 2026-02-18 14:53 – Updated: 2026-05-11 21:56

Title

crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode

Summary

In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode The local variable 'i' is initialized with -EINVAL, but the for loop immediately overwrites it and -EINVAL is never returned. If no empty compression mode can be found, the function would return the out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid array access in add_iaa_compression_mode(). Fix both issues by returning either a valid index or -EINVAL.

Severity

7.1 (High)

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.
