CVE-2026-89821
CVE-2026-89821 updated by NVD
Summary
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.
