CVE-2025-38456

Severity CVSS v4.0:
Pending analysis
Type:
CWE-787 Out-of-bounds Write

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ipmi:msghandler: Fix potential memory corruption in ipmi_create_user()<br /> <br /> The "intf" list iterator is an invalid pointer if the correct<br /> "intf-&gt;intf_num" is not found. Calling atomic_dec(&amp;intf-&gt;nr_users) on<br /> and invalid pointer will lead to memory corruption.<br /> <br /> We don&amp;#39;t really need to call atomic_dec() if we haven&amp;#39;t called<br /> atomic_add_return() so update the if (intf-&gt;in_shutdown) path as well.
