Description OSIDB Bzimport 2026-02-04 17:03:19 UTC 
In the Linux kernel, the following vulnerability has been resolved:

intel_th: fix device leak on output open()

Make sure to drop the reference taken when looking up the th device
during output device open() on errors and on close().

Note that a recent commit fixed the leak in a couple of open() error
paths but not all of them, and the reference is still leaking on
successful open().
