CVE-2026-68180

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> intel_th: fix MSC output device reference leak<br /> <br /> intel_th_output_open() looks up the output device with<br /> bus_find_device_by_devt(), which returns the device with a reference that<br /> must be dropped after use.<br /> <br /> commit 95fc36a234da ("intel_th: fix device leak on output open()")<br /> attempted to drop the reference from intel_th_output_release(). However,<br /> a successful open replaces file-&gt;f_op with the output driver file<br /> operations before returning, so close runs the output driver release<br /> callback instead.<br /> <br /> For MSC outputs, close runs intel_th_msc_release(), which only removes<br /> the per-file iterator and does not drop the device reference taken by<br /> intel_th_output_open(). Consequently, every successful MSC output open<br /> leaks one device reference.<br /> <br /> Drop the device reference from intel_th_msc_release(), which is the<br /> release path actually used for MSC output files. Remove the now-unused<br /> intel_th_output_release() callback from intel_th_output_fops.
