      <title>CVE-2026-68259 — drm/amdkfd: Check bounds in allocate_event_notification_slot</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-68259</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/amdkfd: Check bounds in allocate_event_notification_slot&lt;/p&gt;
&lt;p&gt;The valid event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT&lt;/p&gt;
&lt;p&gt;allocate_event_notification_slot has an option to specify
an event id to allocate at, used by CRIU. We weren&amp;#39;t checking
the bounds on that value.&lt;/p&gt;
&lt;p&gt;Check them.&lt;/p&gt;
&lt;p&gt;v2: Lower bounds check is unecessary because of idr_alloc
already rejecting negative numbers. Upper bounds check should
be KFD_SIGNAL_EVENT_LIMIT since the signal mode mappings might
not yet exist&lt;/p&gt;
&lt;p&gt;(cherry picked from commit 6853f1f6cbbeb3f53ebbbd7286536aeb2c5d5f50)&lt;/p&gt;</description>
