In the Linux kernel, the following vulnerability has been resolved:

arm64: topology: fix possible overflow in amu_fie_setup()

cpufreq_get_hw_max_freq() returns max frequency in kHz as unsigned int,
while freq_inv_set_max_ratio() gets passed this frequency in Hz as ‘u64’.
Multiplying max frequency by 1000 can potentially result in overflow –
multiplying by 1000ULL instead should avoid that…
