[alsa-devel] [PATCH 0/2] More hardening for ALSA sequencer write/ioctl races

Hi,

here is two patches to paper over the still remaining races in ALSA sequencer write and ioctl that have been leaked in the previous fix for CVE-2018-1000004.

The reports came up totally individually, so both people are put as Reported-by tag here.

thanks,

Takashi
