Andy Lutomirski discovered a flaw that allows user to cause the Linux
kernel to ignore some NMIs (non-maskable interrupts). A local unprivileged
user could exploit this flaw to potentially cause the system to miss
important NMIs resulting in unspecified effects. (CVE-2015-3291)
Andy Lutomirski and Petr Matousek discovered that an NMI (non-maskable
interrupt) that interrupts userspace and encounters an IRET fault is
incorrectly handled by the Linux kernel. An unprivileged local user could
exploit this flaw to cause a denial of service (kernel OOPs), corruption,
