CVE-2025-71231: Linux Kernel

High severity, CVSS 7.1. EPSS: 0.1% chance of exploitation in the next 30 days.

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 Linux Kernel: from 6.8, before 6.12.72 (fixed in 6.12.72); from 6.13, before 6.18.11 (fixed in 6.18.11); from 6.19, before 6.19.1 (fixed in 6.19.1)
