CVE-2021-46926
ALSA: hda: intel-sdw-acpi: harden detection of controller
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: intel-sdw-acpi: harden detection of controller
The existing code currently sets a pointer to an ACPI handle before
checking that it's actually a SoundWire controller. This can lead to
issues where the graph walk continues and eventually fails, but the
pointer was set already.
This patch changes the logic so that the information provided to
the caller is set when a controller is found.
