CVE-2015-3290: High severity linux kernel vulnerability
A flaw was found in the way Linux kernel's nested NMI handler and espfix64 functionalities interacted during NMI processing.
A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.
Upstream fix: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9b6e6a8334d56354853f9c255d1395c2ba570e0a
Acknowledgements:
Red Hat would like to thank Andy Lutomirski for reporting this issue.
Other sources
arch/x86/entry/entry64.S in the Linux kernel before 4.1.6 on the x8664 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.
