This will cause a divide-by-zero panic and can also cause an underflow on num_mcaches.</p> <p>Fix this by changing calculate_mcache_setting to bool and adding guards after each calculate_mcache_row_bytes call. If num_mcaches or mvmpg_width/height is zero, return a false. Callers will propagate the failure as a rejected mode, which prevents the panic.</p> <p>(cherry picked from commit 29c0f7c655f47bcbd575ff75e58480df6ec3c9da)</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>drm/amd/display: Fix divide-by-zero in calculate_mcache_setting on zero viewport</p> <p>If a plane reaches calculate_mcache_setting with a zero-area viewport, calculate_mcache_setting exits early with num_mcaches == 0 and mvmpg_width/height == 0.
