Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: imx: Fix an out-of-bounds access in dispmix_csr_clk_dev_data
When num_parents is 4, __clk_register() occurs an out-of-bounds
when accessing parent_names member. Use ARRAY_SIZE() instead of
hardcode number here.
BUG: KASAN: global-out-of-bounds in __clk_register+0x1844/0x20d8
