      <title>CVE-2026-80865 — bpf: Add missing access_ok call to copy_user_syms</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-80865</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: Add missing access_ok call to copy_user_syms&lt;/p&gt;
&lt;p&gt;As reported by sashiko we use __get_user without prior access_ok call on the
user space pointer. Adding the missing call for the whole pointer array.&lt;/p&gt;
&lt;p&gt;Plus removing the err check in the error path, because it&amp;#39;s not needed and
also we can return -ENOMEM directly from the first kvmalloc_array fail path.&lt;/p&gt;
