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/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation This commit addresses a potential index out of bounds issue in the `cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30 color management module. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, the function returns false to indicate an error. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:338 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:339 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:340 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max

Recommended fix High confidence

Upgrade to kernel >= 5.10.227, >= 5.15.168, >= 6.1.113, or >= 6.6.55 depending on your current branch (or latest stable available)

  1. 1. Identify the current running kernel version using 'uname -r'
  2. 2. Determine which upgrade path applies based on your current version (5.10.x, 5.11-5.15.x, 5.16-6.1.x, or 6.2-6.6.x)
  3. 3. For Ubuntu/Debian: Run 'sudo apt update && sudo apt upgrade' to install the latest kernel package
  4. 4. For RHEL/CentOS: Run 'sudo yum update kernel' or 'sudo dnf update kernel'
  5. 5. For other distributions: Obtain a kernel package from your distribution's repositories that meets or exceeds the fixed version for your branch
  6. 6. Reboot the system to load the new kernel: 'sudo reboot'
  7. 7. Verify the new kernel version is running: 'uname -r'
Caveat Kernel upgrades generally do not introduce breaking changes for this type of bug fix; however, verify that any proprietary AMD GPU drivers (e.g., amdgpu-pro) are compatible with the new kernel version
