Recommended fix High confidence

Upgrade to kernel 6.1.135+, 6.6.88+, 6.12.25+, or 6.14.4+ (depending on which stable branch you are on); for Debian 11, install latest available kernel from Debian security updates

  1. Identify the current running kernel version using 'uname -r'
  2. For Debian 11 systems: Run 'apt update' followed by 'apt list --upgradable' to check for kernel updates, or check for security updates via 'apt update && apt upgrade'
  3. If a newer fixed kernel is available (6.1.135+, 6.6.88+, 6.12.25+, or 6.14.4+ depending on your branch), install it with 'apt install linux-image-<version>'
  4. Reboot the system to load the updated kernel
  5. Verify the fix is applied by checking the kernel version after reboot matches a fixed release
Caveat Kernel upgrades may require driver recompilation or system restart; ensure compatibility with custom drivers or hardware before upgrading
