Descriptions

Memory leaks in *clock_source_create() functions under drivers/gpu/drm/amd/display/dc in the Linux kernel before 5.3.8 allow attackers to cause a denial of service (memory consumption). This affects the dce112_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c, the dce100_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c, the dcn10_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.c, the dcn20_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c, the dce120_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c, the dce110_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c, and the dce80_clock_source_create() function in drivers/gpu/drm/amd/display/dc/dce80/dce80_resource.c, aka CID-055e547478a1.

Una pérdida de memoria en las funciones *clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc en el kernel de Linux versiones anteriores a la versión 5.3.8, permite a atacantes causar una denegación de servicio (consumo de memoria). Esto afecta la función dce112_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dce112/dce112_resource.c, la función dce100_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dce100/dce100_resource.c, la función dcn10_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dcn10/dcn10_resource.c, la función dcn20_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dcn20/dcn20_resource.c, la función dce120_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dce120/dce120_resource.c, la función dce110_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dce110/dce110_resource.c, y la función dce80_clock_source_create() en el archivo drivers/gpu/drm/amd/display/dc/dce80/dce80_resource.c, también se conoce como CID-055e547478a1.
