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 https://github.com/torvalds/linux/pull/440 -- You are receiving this mail because: You are the assignee for the bug.
