      <title>CVE-2022-50366 — powercap: intel_rapl: fix UBSAN shift-out-of-bounds issue</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-50366</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;powercap: intel_rapl: fix UBSAN shift-out-of-bounds issue&lt;/p&gt;
&lt;p&gt;When value &amp;lt; time_unit, the parameter of ilog2() will be zero and
the return value is -1. u64(-1) is too large for shift exponent
and then will trigger shift-out-of-bounds:&lt;/p&gt;
&lt;p&gt;shift exponent 18446744073709551615 is too large for 32-bit type &amp;#39;int&amp;#39;
Call Trace:
 rapl_compute_time_window_core
 rapl_write_data_raw
 set_time_window
 store_constraint_time_window_us&lt;/p&gt;</description>
