Vulnerability in Linux Kernel
CVE-2019-19083
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.
