  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: rc: sunxi-cir: Unregister rc device on probe failure\n\nAfter rc_register_device() succeeds, later probe failures must undo the\nregistration with rc_unregister_device(). The current error path jumps to\nthe allocation cleanup label and only calls rc_free_device(), leaving the\nrc device registration and resources created by rc_register_device()\nbehind.\n\nAdd a registered-device unwind label for the IRQ lookup, IRQ request, and\nhardware initialization failure paths. Keep rc_free_device() for failures\nbefore rc_register_device() succeeds.",
