Why Medium

Medium rather than High: exposure is scored at a default because we cannot see your systems or suppliers. If you run or depend on Google Skia, treat it as High.

Briefing

Questions to ask IT

  • Do we run Google Skia, and is every instance on version 146.0.7680.75 or later?
  • Is any of it reachable from the internet?
  • Have we checked whether it has already been used against us?
  • If it is not yet patched, what mitigation is in place, and will the fix be done by 16 Nov?

Next steps

  1. Confirm exposure, mitigation status and any service interruption risk.
