      <title>CVE-2025-68378 — bpf: Fix stackmap overflow check in __bpf_get_stackid()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-68378</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: Fix stackmap overflow check in __bpf_get_stackid()&lt;/p&gt;
&lt;p&gt;Syzkaller reported a KASAN slab-out-of-bounds write in __bpf_get_stackid()
when copying stack trace data. The issue occurs when the perf trace
 contains more stack entries than the stack map bucket can hold,
 leading to an out-of-bounds write in the bucket&amp;#39;s data array.&lt;/p&gt;</description>
