CVE-2014-9903 low priority: Ubuntu including 27 source packages (linux, linux-armadaxp, …), 158 status rows across 6 suites (precise, trusty, upstream, wily, xenial, yakkety): DNE 98, released 27, not-affected 22, ignored 11.
The sched_read_attr function in kernel/sched/core.c in the Linux kernel 3.14-rc before 3.14-rc4 uses an incorrect size, which allows local users to obtain sensitive information from kernel stack memory via a crafted sched_getattr system call.
