Affected: Linux

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().

Affected: Ubuntu:Pro:20.04:LTS: linux-nvidia-tegra-5.15

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.
