  "message": "drm: Replace old pointer to new idr\n\nCommit 5e28b7b94408 introduced a logical error by failing to replace the\nnewly generated IDR pointer to old id\u0027s pointer at the correct location\nwithin the \"change handle\" logic; this resulted in the issue reported by\nsyzbot [1].\n\nSpecifically, the new IDR object pointer is intended to replace the original\nid\u0027s pointer during the normal execution flow.\n\nAdditionally, an unnecessary conditional check for the ret exit path has\nbeen removed.\n\n[1]\n!RB_EMPTY_ROOT(\u0026prime_fpriv-\u003edmabufs)\nWARNING: drivers/gpu/drm/drm_prime.c:224 at drm_prime_destroy_file_private+0x48/0x60 drivers/gpu/drm/drm_prime.c:224, CPU#0: syz.0.17/5833\nCall Trace:\n drm_file_free.part.0+0x7e6/0xcc0 drivers/gpu/drm/drm_file.c:269\n drm_file_free drivers/gpu/drm/drm_file.c:237 [inline]\n drm_close_helper.isra.0+0x186/0x200 drivers/gpu/drm/drm_file.c:290\n drm_release+0x1ab/0x360 drivers/gpu/drm/drm_file.c:438\n\nFixes: 5e28b7b94408 (\"drm: Set old handle to NULL before prime swap in change_handle\")\nReported-by: syzbot+d7c9eed171647e421013@syzkaller.appspotmail.com\nCloses: https://syzkaller.appspot.com/bug?extid\u003dd7c9eed171647e421013\nCc: stable@vger.kernel.org\nTested-by: syzbot+d7c9eed171647e421013@syzkaller.appspotmail.com\nSigned-off-by: Edward Adam Davis \u003ceadavis@qq.com\u003e\nSigned-off-by: Dave Airlie \u003cairlied@redhat.com\u003e\nLink: https://patch.msgid.link/tencent_C267296443AAA4567771176886DFF364A305@qq.com\n",
