Severity CVSS v4.0:
Pending analysis
Type:
CWE-125 Out-of-bounds Read
Publication date:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode<br /> <br /> The local variable &amp;#39;i&amp;#39; is initialized with -EINVAL, but the for loop<br /> immediately overwrites it and -EINVAL is never returned.<br /> <br /> If no empty compression mode can be found, the function would return the<br /> out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid<br /> array access in add_iaa_compression_mode().<br /> <br /> Fix both issues by returning either a valid index or -EINVAL.
