CVE-2022-50810 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: rapidio: devices: fix missing put_device in mport_cdev_open When kfifo_alloc fails, the refcount of chdev->dev is left incremental. We should use put_device(&chdev->dev) to decrease the ref count of chdev->dev to avoid refcount leak.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
