  "description": "In the Linux kernel, the following vulnerability has been resolved:  clk: bcm: dvp: Assign -\u003Enum before accessing -\u003Ehws  Commit f316cdff8d67 (\u0022clk: Annotate struct clk_hw_onecell_data with __counted_by\u0022) annotated the hws member of \u0027struct clk_hw_onecell_data\u0027 with __counted_by, which informs the bounds sanitizer about the number of elements in hws, so that it can warn when hws is accessed out of bounds. As noted in that change, the __counted_by member must be initialized with the number of elements before the first array access happens, otherwise there will be a warning from each access prior to the initialization because the number of elements is zero. This occurs in clk_dvp_probe() due to -\u003Enum being assigned after -\u003Ehws has been accessed:    UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-bcm2711-dvp.c:59:2   index 0 is out of range for type \u0027struct clk_hw *[] __counted_by(num)\u0027 (aka \u0027struct clk_hw *[]\u0027)  Move the -\u003Enum initialization to before the first access of -\u003Ehws, which clears up the warning.",
