      <title>CVE-2024-50201 — drm/radeon: Fix encoder-&gt;possible_clones</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-50201</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;drm/radeon: Fix encoder-&amp;gt;possible_clones&lt;/p&gt;
&lt;p&gt;Include the encoder itself in its possible_clones bitmask.
In the past nothing validated that drivers were populating
possible_clones correctly, but that changed in commit
74d2aacbe840 (&amp;#34;drm: Validate encoder-&amp;gt;possible_clones&amp;#34;).
Looks like radeon never got the memo and is still not
following the rules 100% correctly.&lt;/p&gt;
&lt;p&gt;This results in some warnings during driver initialization:
Bogus possible_clones: [ENCODER:46:TV-46] possible_clones=0x4 (full encoder mask=0x7)
WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drm_mode_config.c:615 drm_mode_config_validate+0x113/0x39c
...&lt;/p&gt;
&lt;p&gt;(cherry picked from commit 3b6e7d40649c0d75572039aff9d0911864c689db)&lt;/p&gt;</description>
