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/panel: ilitek-ili9881c: Fix warning with GPIO controllers that sleep The ilitek-ili9881c controls the reset GPIO using the non-sleeping gpiod_set_value() function. This complains loudly when the GPIO controller needs to sleep. As the caller can sleep, use gpiod_set_value_cansleep() to fix the issue.

Recommended fix High confidence

Kernel 5.15.162 or later (LTS), or 5.10.221, 5.4.279, or 4.19.317 depending on your branch

  1. Identify your current kernel version using `uname -r`
  2. Determine which kernel major version series you are running (e.g., 5.15.x, 5.10.x, 5.4.x, 4.19.x)
  3. Upgrade to a kernel version that includes the fix: for 5.15.x series use >= 5.15.162, for 5.10.x use >= 5.10.221, for 5.4.x use >= 5.4.279, or for 4.19.x use >= 4.19.317
  4. On Debian/Ubuntu: `sudo apt-get update && sudo apt-get install linux-image-<version>`
  5. On RHEL/CentOS: `sudo yum update kernel`
  6. On Fedora: `sudo dnf update kernel`
  7. Reboot into the new kernel: `sudo reboot`
  8. Verify the fix is applied by checking the ilitek-ili9881c driver source or checking kernel version with `uname -r`
Caveat None - this is a bug fix for a warning; upgrading to a newer stable kernel is low risk but ensure compatibility with your hardware and workloads
