  "description": "In the Linux kernel, the following vulnerability has been resolved:  ieee802154: ca8210: Fix a potential UAF in ca8210_probe  If of_clk_add_provider() fails in ca8210_register_ext_clock(), it calls clk_unregister() to release priv-\u003Eclk and returns an error. However, the caller ca8210_probe() then calls ca8210_remove(), where priv-\u003Eclk is freed again in ca8210_unregister_ext_clock(). In this case, a use-after-free may happen in the second time we call clk_unregister().  Fix this by removing the first clk_unregister(). Also, priv-\u003Eclk could be an error code on failure of clk_register_fixed_rate(). Use IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().",
