This update for spectre-meltdown-checker fixes the following issues :

  • feat: implement TAA detection (CVE-2019-11135 bsc#1139073)

  • feat: implement MCEPSC / iTLB Multihit detection (CVE-2018-12207 bsc#1117665)

  • feat: taa: add TSX_CTRL MSR detection in hardware info

  • feat: fwdb: use both Intel GitHub repo and MCEdb to build our firmware version database

  • feat: use --live with --kernel/–config/–map to override file detection in live mode

  • enh: rework the vuln logic of MDS with --paranoid (fixes #307)

  • enh: explain that Enhanced IBRS is better for performance than classic IBRS

  • enh: kernel: autodetect customized arch kernels from cmdline

  • enh: kernel decompression: better tolerance against missing tools

  • enh: mock: implement reading from /proc/cmdline

  • fix: variant3a: Silvermont CPUs are not vulnerable to variant 3a

  • fix: lockdown: detect Red Hat locked down kernels (impacts MSR writes)

  • fix: lockdown: detect locked down mode in vanilla 5.4+ kernels

  • fix: sgx: on locked down kernels, fallback to CPUID bit for detection

  • fix: fwdb: builtin version takes precedence if the local cached version is older

  • fix: pteinv: don’t check kernel image if not available

  • fix: silence useless error from grep (fixes #322)

  • fix: msr: fix msr module detection under Ubuntu 19.10 (fixes #316)
