      <title>CVE-2021-46908 — bpf: Use correct permission flag for mixed signed bounds arithmetic</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2021-46908</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;bpf: Use correct permission flag for mixed signed bounds arithmetic&lt;/p&gt;
&lt;p&gt;We forbid adding unknown scalars with mixed signed bounds due to the
spectre v1 masking mitigation. Hence this also needs bypass_spec_v1
flag instead of allow_ptr_leaks.&lt;/p&gt;</description>
