CVE-2026-89821

CVE-2026-89821 affects the Linux kernel DRM AMD display subsystem. The function __is_lut_linear() computes each LUT entry as i * MAX_DRM_LUT_VALUE / (size - 1). When called with a single-entry LUT , the divisor becomes zero, triggering a kernel divide error (#DE) . Since a LUT with fewer than two...

CVE-2026-89819

CVE-2026-89819 is a Linux kernel vulnerability in the AMD display driver (drm/amd/display). The per-plane degamma LUT size was never validated before use, unlike the CRTC degamma path which is guarded by amdgpu_dm_verify_lut_sizes(). A malformed AMD_PLANE_DEGAMMA_LUT blob could trigger a divide-b...
