Spectre and Meltdown mitigation detection tool v0.35
Checking for vulnerabilities on current system
Kernel is Linux 4.13.0-36-generic #40~16.04.1-Ubuntu SMP Fri Feb 16 23:26:51 UTC 2018 i686
CPU is Pentium(R) Dual-Core CPU E5300 @ 2.60GHz
Hardware check
* Hardware support (CPU microcode) for mitigation techniques
* Indirect Branch Restricted Speculation (IBRS)
* SPEC_CTRL MSR is available: NO
* CPU indicates IBRS capability: NO
* Indirect Branch Prediction Barrier (IBPB)
* PRED_CMD MSR is available: NO
* CPU indicates IBPB capability: NO
* Single Thread Indirect Branch Predictors (STIBP)
* SPEC_CTRL MSR is available: NO
* CPU indicates STIBP capability: NO
* Enhanced IBRS (IBRS_ALL)
* CPU indicates ARCH_CAPABILITIES MSR availability: NO
* ARCH_CAPABILITIES MSR advertises IBRS_ALL capability: NO
* CPU explicitly indicates not being vulnerable to Meltdown (RDCL_NO): NO
* CPU microcode is known to cause stability problems: NO (model 23 stepping 10 ucode 0xa07)
* CPU vulnerability to the three speculative execution attacks variants
* Vulnerable to Variant 1: YES
* Vulnerable to Variant 2: NO
* Vulnerable to Variant 3: YES
CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Mitigated according to the /sys interface: YES (kernel confirms that the mitigation is active)
* Kernel has array_index_mask_nospec: NO
* Kernel has the Red Hat/Ubuntu patch: YES
> STATUS: NOT VULNERABLE (Mitigation: OSB (observable speculation barrier, Intel v6))
CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'
* Mitigated according to the /sys interface: YES (kernel confirms that the mitigation is active)
* Mitigation 1
* Kernel is compiled with IBRS/IBPB support: YES
* Currently enabled features
* IBRS enabled for Kernel space: NO
* IBRS enabled for User space: NO
* IBPB enabled: NO
* Mitigation 2
* Kernel compiled with retpoline option: YES
* Kernel compiled with a retpoline-aware compiler: YES (kernel reports full retpoline compilation)
> STATUS: NOT VULNERABLE (your CPU vendor reported your CPU model as not vulnerable)
CVE-2017-5754 [rogue data cache load] aka 'Meltdown' aka 'Variant 3'
* Mitigated according to the /sys interface: NO (kernel confirms your system is vulnerable)
* Kernel supports Page Table Isolation (PTI): NO
* PTI enabled and active: NO
* Running as a Xen PV DomU: NO
> STATUS: VULNERABLE (PTI is needed to mitigate the vulnerability)
