Intel® SGX SDK Advisory
A potential security vulnerability in Intel® Software Guard Extensions (SGX) SDK may allow escalation of privilege. Intel is releasing software updates to mitigate this potential vulnerability.
Description: Improper initialization in the Intel(R) SGX SDK may allow an authenticated user to potentially enable escalation of privilege via local access.
CVSS Base Score: 2.5 Low
CVSS Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N
Intel® SGX SDK before v22.214.171.124 for Windows*, and
Intel® SGX SDK before v126.96.36.199 for Linux
Intel recommends updating the Intel® SGX SDK for Windows* to v188.8.131.52 or later.
Intel recommends updating the Intel® SGX SDK for Linux to v184.108.40.206 or later.
Updates are available for download at these locations:
Intel® SGX SDK for Windows*:
Intel® SGX SDK for Linux:
For those SGX application enclaves which use floating point, solution developers should recompile their affected enclaves with the updated Intel SGX SDK, and re-issue the application. Affected solution developers should also consider increasing the Security Version Numbers (ISVSVN) of their updated SGX application enclaves.
Developers implementing their own SDK should review the documentation and code changes issued with the Intel SGX SDK for Linux.
