      <title>CVE-2026-68242 — drm/i915/gt: Fix NULL deref on sched_engine alloc failure</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-68242</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/i915/gt: Fix NULL deref on sched_engine alloc failure&lt;/p&gt;
&lt;p&gt;Avoid using intel_context_put() before intel_context_init() in
execlists_create_virtual() as the kref_put() inside would lead
to NULL deref on the IOCTL path when sched_engine allocation fails.&lt;/p&gt;
&lt;p&gt;Discovered using AI-assisted static analysis confirmed by
Intel Product Security.&lt;/p&gt;
&lt;p&gt;(cherry picked from commit 4f2a12f2d50e9f48227656e4dcbd6423506be31d)&lt;/p&gt;</description>
