Description Dhananjay Arunesh 2019-11-27 15:36:52 UTC 
A memory leak in the komeda_wb_connector_add() function in drivers/gpu/drm/arm/display/komeda/komeda_wb_connector.c in the Linux kernel allows attackers to cause a denial of service (memory consumption) by triggering drm_writeback_connector_init() failures.
