Spectre and Meltdown mitigation detection tool v0.31
Checking for vulnerabilities against running kernel Linux 3.14.56 #1 SMP PREEMPT Wed Nov 4 15:19:30 GMT-8 2015 i686
CPU is Pentium III (Coppermine)
Will use vmlinux image vmlinuz
Will use kconfig /proc/config.gz
Will use no System.map file (accuracy might be reduced)
We're missing some kernel info (see -v), accuracy might be reduced
CVE-2017-5753 [bounds check bypass] aka 'Spectre Variant 1'
* Checking count of LFENCE opcodes in kernel: UNKNOWN
> STATUS: UNKNOWN (couldn't check (couldn't find your kernel image in /boot, if you used netboot, this is normal))
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: YES
* The kernel has set the spec_ctrl flag in cpuinfo: 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: UNKNOWN (couldn't find your kernel image or System.map)
> 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
* Performance impact if PTI is enabled
* CPU supports PCID: NO (no security impact but performance will be degraded with PTI)
* CPU supports INVPCID: NO (no security impact but performance will be degraded with PTI)
* Checking if we're running under Xen PV (64 bits): NO
> STATUS: VULNERABLE (PTI is needed to mitigate the vulnerability)
A false sense of security is worse than no security at all, see --disclaimer
