Summary

Multiple NetApp products use x86 architecture. On x86 systems the MOV SS and POP SS instructions inhibit some debug exceptions until the next instruction has completed. This can allow the kernel context to handle debug exceptions instead of the user context. Successful exploitation of this vulnerability by a local authenticated attacker could result in disclosure of sensitive information, escalation of privilege, or cause Denial of Service (DoS).

Impact

Successful exploitation of this vulnerability by a local authenticated attacker could result in disclosure of sensitive information, escalation of privilege, or cause Denial of Service (DoS).
