I couldn’t find a list of #Linux #kernel versions that include a patch for #copyfail, so I dug into the commit log and made one. Make sure you’re using at least the following version of your branch to mitigate against copyfail:

  • 7.0-rc7 (any stable 7.x is safe)
  • 6.19.12
  • 6.18.22
  • 6.12.85
  • 6.6.137
  • 6.1.170
  • 5.15.204
  • 5.10.254

See https://copy.fail for more info about the #exploit.
