Title
usb: typec: tcpm: Check for port partner validity before consuming it
Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: typec: tcpm: Check for port partner validity before consuming it
typec_register_partner() does not guarantee partner registration
to always succeed. In the event of failure, port->partner is set
to the error value or NULL. Given that port->partner validity is
not checked, this results in the following crash:
Unable to handle kernel NULL pointer dereference at virtual address xx
pc : run_state_machine+0x1bc8/0x1c08
lr : run_state_machine+0x1b90/0x1c08
..
Call trace:
run_state_machine+0x1bc8/0x1c08
tcpm_state_machine_work+0x94/0xe4
kthread_worker_fn+0x118/0x328
kthread+0x1d0/0x23c
ret_from_fork+0x10/0x20
To prevent the crash, check for port->partner validity before
derefencing it in all the call sites.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
