In the Linux kernel, the following vulnerability has been resolved:
usb: typec: Fix error pointer dereference
The variable tps->partner is checked for an error pointer and then if it
is, it sends an error message but does not return and then immediately
dereferenced a few lines below:
tps->partner = typec register partner(tps->port, &desc);
if (IS ERR(tps->partner))
dev warn(tps->dev, "%s: failed to register partnet
", func );
if (desc.identity) {
typec partner set identity(tps->partner);
cd321x->cur partner identity = st.partner identity;
}
Add early return and fix spelling mistake in error message.
