  "description": "In the Linux kernel, the following vulnerability has been resolved:  usb: typec: ucsi: ccg: Fix use-after-free of ucsi on remove  The threaded IRQ handler ccg_irq_handler() calls ucsi_notify_common(), which on a connector-change event calls ucsi_connector_change() and schedules connector work.  In ucsi_ccg_remove(), ucsi_destroy() frees uc-\u003Eucsi (kfree) before free_irq() is called, so a handler invocation already in flight may access the freed object after ucsi_destroy().    CPU 0 (remove)            | CPU 1 (threaded IRQ)     ucsi_destroy(uc-\u003Eucsi)  |   ccg_irq_handler()       kfree(ucsi) // FREE   |     ucsi_notify_common(uc-\u003Eucsi) // USE  Move free_irq() before ucsi_destroy() in the remove path.  It is kept after ucsi_unregister(): ucsi_unregister() cancels connector work whose handler issues GET_CONNECTOR_STATUS through ucsi_send_command_common(), which waits for a completion that is signalled from the IRQ handler, so the IRQ must stay active until that work has been cancelled.  The probe error path already orders free_irq() before ucsi_destroy().  This bug was found by static analysis.",
