CVE-2015-3290

Published: 23 July 2015

arch/x86/entry/entry_64.S in the Linux kernel before 4.1.6 on the x86_64 platform improperly relies on espfix64 during nested NMI processing, which allows local users to gain privileges by triggering an NMI within a certain instruction window.

From the Ubuntu security team

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.
