      <title>CVE-2022-49754 — Bluetooth: Fix a buffer overflow in mgmt_mesh_add()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-49754</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;Bluetooth: Fix a buffer overflow in mgmt_mesh_add()&lt;/p&gt;
&lt;p&gt;Smatch Warning:
net/bluetooth/mgmt_util.c:375 mgmt_mesh_add() error: __memcpy()
&amp;#39;mesh_tx-&amp;gt;param&amp;#39; too small (48 vs 50)&lt;/p&gt;
&lt;p&gt;Analysis:&lt;/p&gt;
&lt;p&gt;&amp;#39;mesh_tx-&amp;gt;param&amp;#39; is array of size 48. This is the destination.
u8 param[sizeof(struct mgmt_cp_mesh_send) + 29]; // 19 + 29 = 48.&lt;/p&gt;
&lt;p&gt;But in the caller &amp;#39;mesh_send&amp;#39; we reject only when len &amp;gt; 50.
len &amp;gt; (MGMT_MESH_SEND_SIZE + 31) // 19 + 31 = 50.&lt;/p&gt;</description>
