"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nintel_th: fix MSC output device reference leak\n\nintel_th_output_open() looks up the output device with\nbus_find_device_by_devt(), which returns the device with a reference that\nmust be dropped after use.\n\ncommit 95fc36a234da (\"intel_th: fix device leak on output open()\")\nattempted to drop the reference from intel_th_output_release(). However,\na successful open replaces file->f_op with the output driver file\noperations before returning, so close runs the output driver release\ncallback instead.\n\nFor MSC outputs, close runs intel_th_msc_release(), which only removes\nthe per-file iterator and does not drop the device reference taken by\nintel_th_output_open(). Consequently, every successful MSC output open\nleaks one device reference.\n\nDrop the device reference from intel_th_msc_release(), which is the\nrelease path actually used for MSC output files. Remove the now-unused\nintel_th_output_release() callback from intel_th_output_fops."
