      <title>CVE-2024-47697 — drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-47697</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux, Siemens RUGGEDCOM RST2428P, Siemens SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family, Siemens SCALANCE XCM-/XRM-/XCH-/XRH-300 family, Siemens SIMATIC S7-1500 TM MFP - GNU/Linux subsystem&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;drivers: media: dvb-frontends/rtl2830: fix an out-of-bounds write error&lt;/p&gt;
&lt;p&gt;Ensure index in rtl2830_pid_filter does not exceed 31 to prevent
out-of-bounds access.&lt;/p&gt;
&lt;p&gt;dev-&amp;gt;filters is a 32-bit value, so set_bit and clear_bit functions should
only operate on indices from 0 to 31. If index is 32, it will attempt to
access a non-existent 33rd bit, leading to out-of-bounds access.
Change the boundary check from index &amp;gt; 32 to index &amp;gt;= 32 to resolve this
issue.&lt;/p&gt;</description>
