"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nclk: mediatek: pllfh: Fix IO remapping leak in register_pllfhs error path\n\nWhen mtk_clk_register_pllfhs function fails to register a PLL, it\nunregisters all PLLs and cleans up itself in its error path before\nreturning, so the function callers don't need to do it.\n\nBut contrary to mtk_clk_unregister_pllfhs function, that does almost\nthe same sequence, it does not free the IO memory mapped on fhctl node,\nleading to a leak.\n\nFix this leak by factorizing the cleanup sequence in a new private\nfunction and use it both mtk_clk_register_pllfhs and\nmtk_clk_unregister_pllfhs functions.\n\nAlso, change the loop index start value to avoid the -1 operation on\nindex at each loop."
