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