  "summary": "Updated kernel packages fix security vulnerabilities",
  "details": "This update is based on upstream 5.4.6 and fixes various potential\nsecurity issues related to buffer overflows, double frees, NUll  pointer\ndereferences, improper / missing input validations and so on. It also\nadds other bugfixes all over the kernel.\n\nOther fixes added in this update:\n- x86/MCE/AMD: Do not use rdmsr_safe_on_cpu() in smca_configure(),\n  fixing an deadlock issue.\n- x86/mm: Split vmalloc_sync_all(), fixing up big performance\n  regressions in some x86_64 workloads \n  (example: reaim.jobs_per_min -79.7% regression) \n- The Intel cpu/gpu specific security fixes in upstream 5.3.11 broke\n  RC6 and that prevents CPUs from entering C-states, causing higher\n  power consumption. This update adds upstream fixes to restore\n  RC6 to a working state (fdo#112315)\n- radeon changes in upstream 5.4 to remove the 'need_dma32 flag' has\n  been reverted as it caused radeon to malfunction on 32bit kernels\n- iwlwifi fixes for firmware crashes (mga#25926), failures on warm\n  reboot, and performance fixes\n\nWireGuard has been updated to 0.0.20191219.\n\nFor other fixes in this update, see the referenced changelogs.\n",
