CVE-2024-49894

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix index out of bounds in degamma hardware format translation Fixes index out of bounds issue in `cm_helper_translate_curve_to_degamma_hw_format` function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds the function returns false to indicate an error. Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:595 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:596 cm_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Corrige el índice fuera de los límites en la traducción del formato de hardware degamma Corrige el problema del índice fuera de los límites en la función `cm_helper_translate_curve_to_degamma_hw_format`. El problema podría ocurrir cuando el índice 'i' excede el número de puntos de función de transferencia (TRANSFER_FUNC_POINTS). La corrección agrega una verificación para garantizar que 'i' esté dentro de los límites antes de acceder a los puntos de función de transferencia. Si 'i' está fuera de los límites, la función devuelve falso para indicar un error. Reportado por smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:594 cm_helper_translate_curve_to_degamma_hw_format() error: desbordamiento de búfer 'output_tf-&gt;tf_pts.red' 1025 &lt;= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:595 cm_helper_translate_curve_to_degamma_hw_format() error: desbordamiento de búfer 'output_tf-&gt;tf_pts.green' 1025 &lt;= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:596 cm_helper_translate_curve_to_degamma_hw_format() error: desbordamiento de búfer 'output_tf-&gt;tf_pts.blue' 1025 &lt;= s32max
