      <title>CVE-2026-15466 — GPU DDK - Write UAF due to a race condition caused by insufficient locking in PVRSRVRGXCloseHWPerfClientStreamKM()</title>
      <link>https://db.gcve.eu/vuln/cve-2026-15466</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Imagination Technologies Graphics DDK&lt;/p&gt;
&lt;p&gt;Software installed and run as a non-privileged user may conduct improper GPU system calls to cause race condition in hardware performance counters buffer’s destruction path leading to read and/or write UAF.&lt;/p&gt;
&lt;p&gt;The race condition in the destruction path could lead to reference counter being decremented in non-atomical way allowing other code paths using a freed object to read and/or write kernel heap memory.&lt;/p&gt;</description>
