Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: drm/i915: Make intel_get_crtc_new_encoder() less oopsy The point of the WARN was to print something, not oops straight up. Currently that is precisely what happens if we can't find the connector for the crtc in the atomic state. Get the dev pointer from the atomic state instead of the potentially NULL encoder to avoid that. (cherry picked from commit 3b6692357f70498f617ea1b31a0378070a0acf1c)

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Recommended fix High confidence

Kernel version >= 5.10.180, >= 5.15.111, >= 6.1.28, or >= 6.2.15 (depending on your branch)

  1. Identify your current kernel version using 'uname -r' or 'cat /proc/version'
  2. Backup important data before kernel upgrade
  3. For RHEL/CentOS systems: run 'sudo yum update' or 'sudo dnf update' to get the latest kernel package
  4. For Ubuntu/Debian systems: run 'sudo apt update && sudo apt upgrade' to install the latest kernel
  5. For SUSE systems: run 'sudo zypper update' to get the latest kernel
  6. Alternatively, manually download and install the kernel package for your distribution from your vendor's repositories
  7. After upgrade, reboot the system to load the new kernel: 'sudo reboot'
  8. Verify the new kernel version is running: 'uname -r'
Caveat Kernel upgrades may introduce compatibility issues with custom drivers or modules; ensure all kernel modules are compatible with the new version before rebooting
