CVE-2024-36893

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

typec_register_partner() does not guarantee partner registration
to always succeed. In the event of failure, port->partner is set
to the error value or NULL. Given that port->partner validity is
not checked, this results in the following crash:
