CVE-2024-49894

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/amd/display: Fix index out of bounds in degamma hardware format translation<br /> <br /> Fixes index out of bounds issue in<br /> `cm_helper_translate_curve_to_degamma_hw_format` function. The issue<br /> could occur when the index &amp;#39;i&amp;#39; exceeds the number of transfer function<br /> points (TRANSFER_FUNC_POINTS).<br /> <br /> The fix adds a check to ensure &amp;#39;i&amp;#39; is within bounds before accessing the<br /> transfer function points. If &amp;#39;i&amp;#39; is out of bounds the function returns<br /> false to indicate an error.<br /> <br /> Reported by smatch:<br /> drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow &amp;#39;output_tf-&gt;tf_pts.red&amp;#39; 1025 tf_pts.green&amp;#39; 1025 tf_pts.blue&amp;#39; 1025
