In the Linux kernel, the following vulnerability has been resolved: clk: bcm: rpi: 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 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 raspberrypidiscoverclocks() due to ->num being assigned after ->hws has been accessed: UBSAN: array-index-out-of-bounds in drivers/clk/bcm/clk-raspberrypi.c:374:4 index 3 is out of range for type 'struct clkhw *[] _countedby(num)' (aka 'struct clkhw *[]') Move the ->num initialization to before the first access of ->hws, which clears up the warning.
