arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform does not properly determine when nested NMI processing is occurring, which allows local users to cause a denial of service (skipped NMI) by modifying the rsp register, issuing a syscall instruction, and triggering an NMI.

CVE-2015-3291 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the kernel.
Andy Lutomirski discovered a flaw in the Linux kernel's handling of nested
NMIs (non-maskable interrupts). An unprivileged local user could exploit
this flaw to cause a denial of service (system crash) or potentially
escalate their privileges. (CVE-2015-3290)
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)
