Overview

CVE-2025-71231 is a high-severity vulnerability. It was published on February 18, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
