      <title>CVE-2022-48657 — arm64: topology: fix possible overflow in amu_fie_setup()</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-48657</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;arm64: topology: fix possible overflow in amu_fie_setup()&lt;/p&gt;
&lt;p&gt;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 &amp;#39;u64&amp;#39;.
Multiplying max frequency by 1000 can potentially result in overflow --
multiplying by 1000ULL instead should avoid that...&lt;/p&gt;
&lt;p&gt;Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.&lt;/p&gt;</description>
