Vulnerability from variot
Uncontrolled resource consumption in the Linux kernel drivers for Intel(R) SGX may allow an authenticated user to potentially enable denial of service via local access. Intel Software Guard Extensions (SGX) is a set of security-related instructions from Intel Corporation, which is built into some Intel CPUs. It provides hardware-based memory encryption to isolate application-specific code and data in memory. An authenticated user could exploit this vulnerability to implement a denial of service attack
