      <title>CVE-2025-21653 — net_sched: cls_flow: validate TCA_FLOW_RSHIFT attribute</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-21653</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux, Siemens SIMATIC S7-1500 TM MFP - BIOS, 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;net_sched: cls_flow: validate TCA_FLOW_RSHIFT attribute&lt;/p&gt;
&lt;p&gt;syzbot found that TCA_FLOW_RSHIFT attribute was not validated.
Right shitfing a 32bit integer is undefined for large shift values.&lt;/p&gt;
&lt;p&gt;UBSAN: shift-out-of-bounds in net/sched/cls_flow.c:329:23
shift exponent 9445 is too large for 32-bit type &amp;#39;u32&amp;#39; (aka &amp;#39;unsigned int&amp;#39;)
