Summary
usb: typec: tcpm: fix use-after-free case in tcpm_register_source_caps
Details

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: tcpm: fix use-after-free case in tcpmregistersource_caps

There could be a potential use-after-free case in tcpmregistersourcecaps(). This could happen when: * new (say invalid) source caps are advertised * the existing source caps are unregistered * tcpmregistersourcecaps() returns with an error as usbpowerdeliveryregistercapabilities() fails

This causes port->partnersourcecaps to hold on to the now freed source caps.

Reset port->partnersourcecaps value to NULL after unregistering existing source caps.
