CVE-2019-18810 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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 before 5.3.8 allows attackers to cause a denial of service (memory consumption) by triggering drm_writeback_connector_init() failures, aka CID-a0ecd6fdbf5d.. EPSS estimates a 3.29% chance of exploitation in the next 30 days.
