CVE-2021-47310 is a use-after-free vulnerability in the Linux kernel TI ThunderLAN (tlan) network-driver removal path. In tlan_remove_one(), the driver accessed its netdev private data after free_netdev() had released the network-device object containing that data. The fix defers free_netdev() until the end of the removal function, preventing subsequent accesses to freed private data.
