{"id":"AZL-101666","summary":"CVE-2026-90027 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: qcom-pmic-typec: disable cc_debounce_dwork on stop\n\ncc_debounce_dwork is queued from the set_cc() and start_toggling()\ncallbacks, which run from TCPM's kthread worker.  port_stop() returns\nbefore tcpm_unregister_port() destroys that worker.  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.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:17:15Z","upstream":["CVE-2026-90027"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90027"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-101666.json"}}],"schema_version":"1.9.0"}
