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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":205003,"id":"CVE-2026-90027","ts":1789570702777,"field":"cvss","old":null,"new":"7.8"},{"seq":205002,"id":"CVE-2026-90027","ts":1789570702777,"field":"severity","old":"none","new":"high"}]}
