Flushing the worker\nduring unregister may therefore run a callback which queues the delayed\nwork after port_stop() has returned.\n\nThe delayed work can then run after devres has freed pmic_typec_port.\n\nUse disable_delayed_work_sync() in port_stop() to cancel a pending\ninstance and prevent the TCPM callbacks from queueing another one.\n\nThis issue was found by an in-house static analysis tool.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1ab669c2b44e1040ddfab7cd7f717aad580d17aa","tags":[]},{"url":"https://git.kernel.org/stable/c/263f7d61a4201cde16849b2d016251806e7418be","tags":[]},{"url":"https://git.kernel.org/stable/c/4359b5f95c93a4658e08368fa6fab9d89eb98447","tags":[]},{"url":"https://git.kernel.org/stable/c/c614d7c44ca7fb78867ba46b233acdb59287e8c8","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
