      <title>CVE-2025-22067 — spi: cadence: Fix out-of-bounds array access in cdns_mrvl_xspi_setup_clock()</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-22067</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;spi: cadence: Fix out-of-bounds array access in cdns_mrvl_xspi_setup_clock()&lt;/p&gt;
&lt;p&gt;If requested_clk &amp;gt; 128, cdns_mrvl_xspi_setup_clock() iterates over the
entire cdns_mrvl_xspi_clk_div_list array without breaking out early,
causing &amp;#39;i&amp;#39; to go beyond the array bounds.&lt;/p&gt;
&lt;p&gt;Fix that by stopping the loop when it gets to the last entry, clamping
the clock to the minimum 6.25 MHz.&lt;/p&gt;
&lt;p&gt;Fixes the following warning with an UBSAN kernel:&lt;/p&gt;
&lt;p&gt;vmlinux.o: warning: objtool: cdns_mrvl_xspi_setup_clock: unexpected end of section .text.cdns_mrvl_xspi_setup_clock&lt;/p&gt;</description>
