Description:
 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.
Ubuntu-Description:
 It was discovered that the AMD Display Engine Driver in the Linux kernel
 did not properly deallocate memory in certain error conditions. A local
 attack could use this to cause a denial of service (memory exhaustion).
