Subject: Linux kernel: net/irda/af_irda.c: irda_getsockopt() stack infoleak
net/irda/af_irda.c
Sometimes irda_getsockopt() doesn't initialize all members of list field of irda_device_list struct. This structure is then copied to
userland. It leads to leaking of contents of kernel stack memory. We have to initialize them to zero , or it will allows local users to obtain potentially sensitive information from kernel stack memory by reading a copy of this structure
