Title

usb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stop

Summary

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.

Severity

Use-after-free bugs are AC:L unless the attacker cannot influence the race.\nPR:L - Highest reasonable exposure is a local account on Qualcomm phones, automotive, and embedded boards that manage the Type-C/USB stack, where platform unbind or USB HAL access is often delegated beyond init-namespace root. Uncertain Low versus High, so Low per the overestimate rule.\nUI:N - The attacker initiates driver unbind, module unload, or a failing re-probe themselves; no separate victim action such as plugging a USB-C cable, mounting a filesystem, or opening a device node is required.\nS:U - The use-after-free corrupts the host kernel pmic_typec_port heap object within the same OS security authority and does not cross a VM, IOMMU, or sandbox boundary.\nC:H - qcom_pmic_typec_port_cc_debounce() recovers the freed pmic_typec_port via container_of and reads its spinlock and device pointer; per CNA guidance a use-after-free enables arbitrary kernel memory disclosure.\nI:H - The same delayed work writes debouncing_cc and performs spin_lock/unlock on the freed object, and the pending delayed_work lives inside pmic_typec_port, so heap spray yields an arbitrary write or workqueue function-pointer hijack.\nA:H - Use-after-free of pmic_typec_port from system-wq delayed work after remove causes a kernel oops or panic even without a full exploit, so availability impact is High."

GHSA-FM22-HCRQ-M39W

Vulnerability from github – Published: 2026-09-16 12:30 – Updated: 2026-09-16 15:31

Details

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.

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.
