      <title>CVE-2022-50538 — vme: Fix error not catched in fake_init()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-50538</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;vme: Fix error not catched in fake_init()&lt;/p&gt;
&lt;p&gt;In fake_init(), __root_device_register() is possible to fail but it&amp;#39;s
ignored, which can cause unregistering vme_root fail when exit.&lt;/p&gt;
&lt;p&gt;general protection fault,
 probably for non-canonical address 0xdffffc000000008c
 KASAN: null-ptr-deref in range [0x0000000000000460-0x0000000000000467]
 RIP: 0010:root_device_unregister+0x26/0x60
 Call Trace:
  &amp;lt;TASK&amp;gt;
  __x64_sys_delete_module+0x34f/0x540
  do_syscall_64+0x38/0x90
  entry_SYSCALL_64_after_hwframe+0x63/0xcd&lt;/p&gt;
&lt;p&gt;Return error when __root_device_register() fails.&lt;/p&gt;</description>
