Other sources

Memory leaks in createresourcepool() functions under drivers/gpu/drm/amd/display/dc in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption). This affects the dce120createresourcepool() function in drivers/gpu/drm/amd/display/dc/dce120/dce120resource.c, the dce110createresourcepool() function in drivers/gpu/drm/amd/display/dc/dce110/dce110resource.c, the dce100createresourcepool() function in drivers/gpu/drm/amd/display/dc/dce100/dce100resource.c, the dcn10createresourcepool() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10resource.c, and the dce112createresourcepool() function in drivers/gpu/drm/amd/display/dc/dce112/dce112resource.c, aka CID-104c307147ad.
