CVE-2025-71231: crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode

• Severity: high (CVSS 7.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-125

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.

Affected products

• Linux kernel: from 6.8 before 6.12.72; from 6.13 before 6.18.11; from 6.19 before 6.19.1 — fixed in 6.12.72, 6.18.11, 6.19.1

How to fix

Upgrade to a fixed version: Linux kernel 6.12.72, 6.18.11, 6.19.1. Check the vendor advisory for mitigations.
