Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
drm: Replace old pointer to new idr<br />
<br />
Commit 5e28b7b94408 introduced a logical error by failing to replace the<br />
newly generated IDR pointer to old id&#39;s pointer at the correct location<br />
within the "change handle" logic; this resulted in the issue reported by<br />
syzbot [1].<br />
<br />
Specifically, the new IDR object pointer is intended to replace the original<br />
id&#39;s pointer during the normal execution flow.<br />
<br />
Additionally, an unnecessary conditional check for the ret exit path has<br />
been removed.<br />
