Details

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\n", 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.

Detected by Smatch: drivers/usb/typec/tipd/core.c:827 cd321x_update_work() error: 'tps->partner' dereferencing possible ERR_PTR()
