  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: thunderbolt: Disable work before freeing tbt on remove\n\ntbt_altmode_remove() drops the plug and cable references without\ndraining tbt-\u003ework. The work function dereferences those references,\nand can also requeue itself in its error path. The VDM callbacks can\nqueue the same work item.\n\nDisable and drain tbt-\u003ework before dropping the references. This waits\nfor an existing invocation and prevents subsequent schedule_work()\ncalls from queueing it during teardown.\n\nThis issue was found by an in-house static analysis tool and confirmed\nby manual code review.",
