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.
