Other sources

Memory leaks in clocksourcecreate() 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 dce112clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dce112/dce112resource.c, the dce100clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dce100/dce100resource.c, the dcn10clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dcn10/dcn10resource.c, the dcn20clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dcn20/dcn20resource.c, the dce120clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dce120/dce120resource.c, the dce110clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dce110/dce110resource.c, and the dce80clocksourcecreate() function in drivers/gpu/drm/amd/display/dc/dce80/dce80resource.c, aka CID-055e547478a1.
