In the Linux kernel, the following vulnerability has been resolved:
hwrng: ks-sa - fix division by zero in ks_sa_rng_init
Fix division by zero in ks_sa_rng_init caused by missing clock
pointer initialization. The clk_get_rate() call is performed on
an uninitialized clk pointer, resulting in division by zero when
calculating delay values.
Add clock initialization code before using the clock.
