This  \nordering can trigger a NULL pointer dereference in the serdev controller's  \nreceive_buf handler, as it assumes serdev->ops is valid when  \nSERPORT_ACTIVE is set.  \n  \nThis is similar to the issue fixed in commit 5e700b384ec1  \n(\"platform/chrome: cros_ec_uart: properly fix race condition\") where  \ndevm_serdev_device_open() was called before fully initializing the  \ndevice.  \n  \nFix the race by ensuring client ops are set before enabling the port via  \ndevm_serdev_device_open().  \n  \nNote, serdev_device_set_baudrate() and serdev_device_set_flow_control()  \ncalls should be after the devm_serdev_device_open() call. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"09 Feb 2025\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2025-02-09T14:19:36.000000Z"}
