Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation :
CVE-2014-3144/ CVE-2014-3145 A local user can cause a denial of service (system crash) via crafted BPF instructions.
CVE-2014-3153 Pinkie Pie discovered an issue in the futex subsystem that allows a local user to gain ring 0 control via the futex syscall. An unprivileged user could use this flaw to crash the kernel (resulting in denial of service) or for privilege escalation.
