Spectre and Meltdown mitigation detection tool v0.34+
Checking for vulnerabilities on current system
Kernel is Linux 4.4.0-112-generic #135-Ubuntu SMP Fri Jan 19 11:48:36 UTC
2018 x86_64
CPU is AMD Athlon(tm) II X4 630 Processor
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
* CPU vulnerability to the three speculative execution attacks variants
* Vulnerable to Variant 1: YES
* Vulnerable to Variant 2: YES
* Vulnerable to Variant 3: NO
CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Kernel has array_index_mask_nospec: NO
* Checking count of LFENCE instructions following a jump in kernel...
YES (71 jump-then-lfence instructions found, which is >= 30 (heuristic))
Post by fandangoSTATUS: NOT VULNERABLE (Kernel source has PROBABLY been patched to
mitigate the vulnerability (jump-then-lfence instructions heuristic))
CVE-2017-5715 [branch target injection] aka 'Spectre Variant 2'
* 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: NO
* Kernel compiled with a retpoline-aware compiler: NO
* Retpoline enabled: NO
Post by fandangoSTATUS: 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): YES
* PTI enabled and active: NO
* Running as a Xen PV DomU: NO
Post by fandangoSTATUS: NOT VULNERABLE (your CPU vendor reported your CPU model as
not vulnerable)
