Linux Kernel: iaa Crypto Fix OutofBounds Index Vulnerability
CVE-2025-71231 Published on February 18, 2026
crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode
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.
