CVE-2019-18810 in Ubuntu

CVE-2019-18810

Priority

Description

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.

Ubuntu-Description

It was discovered that the ARM Komeda display driver for the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
