usb: typec: tcpm: Fix NULL pointer dereference in tcpm_pd_svdm()
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) ...
