Severity CVSS v4.0:
Pending analysis
Type:
CWE-415 Double Free
Publication date:
09/11/2024
Last modified:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvmet-auth: assign dh_key to NULL after kfree_sensitive<br /> <br /> ctrl-&gt;dh_key might be used across multiple calls to nvmet_setup_dhgroup()<br /> for the same controller. So it&amp;#39;s better to nullify it after release on<br /> error path in order to avoid double free later in nvmet_destroy_auth().<br /> <br /> Found by Linux Verification Center (linuxtesting.org) with Svace.
