In the Linux kernel, the following vulnerability has been resolved:  clk: samsung: exynos-clkout: Assign .num before accessing .hws  Commit f316cdff8d67 ("clk: Annotate struct clkhwonecelldata with countedby") annotated the hws member of 'struct clkhwonecelldata' with countedby, which informs the bounds sanitizer (UBSANBOUNDS) 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 countedby 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 exynosclkoutprobe() due to .num being assigned after .hws[] has been accessed:    UBSAN: array-index-out-of-bounds in drivers/clk/samsung/clk-exynos-clkout.c:178:18   index 0 is out of range for type 'clk_hw []'  Move the .num initialization to before the first access of .hws[], clearing up the warning.
