CVE-2015-5157
CVE-2015-5157 affects the Linux kernel prior to 4.1.6 on x86_64. The issue is in arch/x86/entry/entry_64.S where IRET faults during NMIs that occur in userspace are mishandled, potentially allowing a local user to gain privileges. The vulnerability is described in several connected advisories as ...

CVE-2015-3290
The connected Astra Linux bulletin describes CVE-2015-3290 in the Linux kernel context and confirms the vulnerability fix: limiting the Haswell performance counter period to mitigate NMI-related privilege escalation. It documents that the issue stemmed from a too-small initial frequency-estimatio...
CVE-2015-3291
CVE-2015-3291 concerns the Linux kernel before 4.1.6 on the x86_64 platform. The issue is that nested NMI processing is not properly detected, allowing a local attacker to trigger a denial of service (skipped NMI) by manipulating the rsp register, issuing a syscall, and triggering an NMI. Affecte...
