[1;34mSpectre and Meltdown mitigation detection tool v0.30[0m | |
Checking for vulnerabilities against running kernel [35mLinux 4.14.13-1-ARCH #1 SMP PREEMPT Wed Jan 10 11:14:50 UTC 2018 x86_64[0m | |
CPU is[35m Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz[0m | |
[1;34mCVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'[0m | |
* Checking count of LFENCE opcodes in kernel: [101m[30m NO [0m | |
> [46m[30mSTATUS:[0m [101m[30m VULNERABLE [0m (only 21 opcodes found, should be >= 70, heuristic to be improved when official patches become available) | |
[1;34mCVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'[0m | |
* Mitigation 1 | |
* Hardware (CPU microcode) support for mitigation | |
* The SPEC_CTRL MSR is available: [102m[30m YES [0m | |
* The SPEC_CTRL CPUID feature bit is set: [102m[30m YES [0m | |

* Mitigation 2 | |
* Kernel compiled with retpoline option: [101m[30m NO [0m | |
* Kernel compiled with a retpoline-aware compiler: [101m[30m NO [0m | |
> [46m[30mSTATUS:[0m [101m[30m VULNERABLE [0m (IBRS hardware + kernel support OR kernel with retpoline are needed to mitigate the vulnerability) | |
