  3. CVE-2024-49895
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix index out of bounds in DCN30 degamma hardware format translation This commit addresses a potential index out of bounds issue in the `cm3_helper_translate_curve_to_degamma_hw_format` function in the DCN30 color management module. 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/dcn30/dcn30_cm_common.c:338 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:339 cm3_helper_translate_curve_to_degamma_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_cm_common.c:340 cm3_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: Se corrige el índice fuera de los límites en la traducción del formato de hardware degamma de DCN30. Esta confirmación aborda un posible problema de índice fuera de los límites en la función `cm3_helper_translate_curve_to_degamma_hw_format` en el módulo de administración de color DCN30. El problema podría ocurrir cuando el índice 'i' excede la cantidad 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.
