CWE ID 770

Summary

CVE-2023-3439 is a vulnerability affecting the MCTP protocol in the Linux kernel. This issue arises due to a flaw in the mctp_unregister() function, which prematurely frees the device's resources when a netcard detaches. If a running routine remains oblivious to this event, it may continue to use the mdev->addrs object, resulting in a use-after-free condition. The consequences of this vulnerability could potentially lead to a denial of service.
