Summary
CVE-2026-89821 affecting package kernel 6.6.150.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: avoid divide-by-zero in __is_lut_linear()

__is_lut_linear() computes the expected value of each entry with

expected = i * MAX_DRM_LUT_VALUE / (size - 1);

If it is ever called with a single-entry LUT, size - 1 is zero and the kernel takes a divide error (#DE). A LUT with fewer than two entries cannot describe a linear mapping anyway, so return false early instead of dividing by zero.
