      <title>CVE-2022-48648 — sfc: fix null pointer dereference in efx_hard_start_xmit</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2022-48648</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;sfc: fix null pointer dereference in efx_hard_start_xmit&lt;/p&gt;
&lt;p&gt;Trying to get the channel from the tx_queue variable here is wrong
because we can only be here if tx_queue is NULL, so we shouldn&amp;#39;t
dereference it. As the above comment in the code says, this is very
unlikely to happen, but it&amp;#39;s wrong anyway so let&amp;#39;s fix it.&lt;/p&gt;
&lt;p&gt;I hit this issue because of a different bug that caused tx_queue to be
NULL. If that happens, this is the error message that we get here:
  BUG: unable to handle kernel NULL pointer dereference at 0000000000000020
  [...]
  RIP: 0010:efx_hard_start_xmit+0x153/0x170 [sfc]&lt;/p&gt;</description>
