In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: Fix null pointer dereference in trace
ucsiregisteraltmode checks ISERR for the alt pointer and treats NULL as valid. When CONFIGTYPECDPALTMODE is not enabled, ucsiregisterdisplayport returns NULL which causes a NULL pointer dereference in trace. Rather than return NULL, call typecportregisteraltmode to register DisplayPort alternate mode as a non-controllable mode when CONFIGTYPECDPALTMODE is not enabled.
