AI risk analysis

Summary: This vulnerability allows for potential race conditions in the USB Type-C PMIC driver, which could lead to unauthorized operations if exploited.
Exploitability: Exploitation requires the attacker to have the ability to trigger the set_cc() and start_toggling() callbacks while the port_stop() is in progress, making it moderately difficult.
Blast radius: If exploited, this could result in unauthorized access or control over the USB Type-C port, potentially leading to data theft or system compromise.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to the fixed version 5.15.110 or later.

NVD description

In the Linux kernel, the following vulnerability has been resolved: usb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stop cc_debounce_dwork is queued from the set_cc() and start_toggling() callbacks, which run from TCPM's kthread worker. port_stop() returns before tcpm_unregister_port() destroys that worker. Flushing the worker during unregister may therefore run a callback which queues the delayed work after port_stop() has returned. The delayed work can then run after devres has freed pmic_typec_port. Use disable_delayed_work_sync() in port_stop() to cancel a pending instance and prevent the TCPM callbacks from queueing another one. This issue was found by an in-house static analysis tool.
