Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: Fix NULL pointer dereference in tcpm_pd_svdm()
It is possible that typec_register_partner() returns ERR_PTR on failure.
When port->partner is an error, a NULL pointer dereference may occur as
shown below.
[91222.095236][ T319] typec port0: failed to register partner (-17)
...
