  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: frequency: adf4377: Fully initialize clk_init_data and clk_parent_data\n\nThe clk_init_data structure contains several mutually-exclusive members\nfor different methods to specify the possible parents of a clock,\nprompting drivers to initialize only the members they need.  However,\nnot initializing all members may cause subtle issues, which are only\nexposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is\nenabled.\n\nadf4377_clk_register() fills in init.parent_data, and assumes that\ninit.parent_names is NULL.  However, the latter is uninitialized, and\nthus may cause a crash.\n\nSimilarly, adf4377_clk_register() fills in only parent_data.fw_name,\nleaving other members of the clk_parent_data structure uninitialized.\n\nMake sure all members are fully initialized, to fix such bugs, and to\navoid future breakage when converting drivers to a different method for\nspecifying the parents.",
