Vulnerability from github – Published: 2026-06-24 18:32 – Updated: 2026-07-15 15:32In 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.
