Spectre and Meltdown mitigation detection tool v0.31
Checking for vulnerabilities against running kernel Linux 2.6.32-5-686-bigmem #1 SMP Tue May 13 16:55:48 UTC 2014 i686
CPU is Intel(R) Xeon(R) CPU E5-2640 v3 @ 2.60GHz
CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Checking count of LFENCE opcodes in kernel: NO
> STATUS: VULNERABLE (only 22 opcodes found, should be >= 70, heuristic to be improved when official patches become available)
CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'
* Mitigation 1
* Hardware (CPU microcode) support for mitigation
* The SPEC_CTRL MSR is available: NO
* The SPEC_CTRL CPUID feature bit is set: NO
* Kernel support for IBRS: NO
* IBRS enabled for Kernel space: NO
* IBRS enabled for User space: NO
* Mitigation 2
* Kernel compiled with retpoline option: NO
* Kernel compiled with a retpoline-aware compiler: NO
> STATUS: VULNERABLE (IBRS hardware + kernel support OR kernel with retpoline are needed to mitigate the vulnerability)
CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3'
* Kernel supports Page Table Isolation (PTI): NO
* PTI enabled and active: NO
* Checking if we're running under Xen PV (64 bits): NO
> STATUS: VULNERABLE (PTI is needed to mitigate the vulnerability)
