Privilege escalation can occur in Linux due to nested NMIs interrupting espfix64.
f62af298234e655a737d78137c9a21203b3fc70e674b757e92ae2c2517d1fb97Ubuntu Security Notice 2700-1 - 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. 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. Various other issues were also addressed.
