      <title>CVE-2022-49262 — crypto: octeontx2 - remove CONFIG_DM_CRYPT check</title>
      <link>https://db.gcve.eu/vuln/cve-2022-49262</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;crypto: octeontx2 - remove CONFIG_DM_CRYPT check&lt;/p&gt;
&lt;p&gt;No issues were found while using the driver with dm-crypt enabled. So
CONFIG_DM_CRYPT check in the driver can be removed.&lt;/p&gt;
&lt;p&gt;This also fixes the NULL pointer dereference in driver release if
CONFIG_DM_CRYPT is enabled.&lt;/p&gt;
&lt;p&gt;...
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000008
...
Call trace:
 crypto_unregister_alg+0x68/0xfc
 crypto_unregister_skciphers+0x44/0x60
 otx2_cpt_crypto_exit+0x100/0x1a0
 otx2_cptvf_remove+0xf8/0x200
 pci_device_remove+0x3c/0xd4
